These hydroxyl-terminated polybutadiene (HTPB) resins are characterized by low volatiles content, low glass transition temperatures, excellent hydrophobicity and a high level of reactive functionality. The facile reaction of Poly bd® and Krasol® polyols with curing agents such as di- and polyisocyanates provides an attractive route to the preparation of general-purpose polyurethane elastomers. The unique structure of the Poly bd® and Krasol® polyols provide properties which surpass typical polyether and polyester polyol based urethane systems, as well as conventional, general-purpose rubbers. Most grades of Poly bd® and Krasol® resins contain unsaturated double bonds (except Krasol® HLBH-P 2000 and Krasol® HLBH-P 3000) that can be cured or crosslinked. Several grades of Poly bd® resin, such as Poly bd® 600E and Poly bd® 605E contain epoxy functionality in the backbone. Krasol® LBH2040 contains additional hydroxyl functions in the backbone. Some of the outstanding performance characteristics Poly bd® and Krasol® resins provide to polyurethanes include: Adhesion to a variety of substrates Hydrolytic stability Resistance to strong aqueous acid and bases Low temperature flexibility Low moisture vapor transmission rates (MVTR) Low embedment stress Thermal cycling stability Electrical insulation properties High elongation with good elastic recovery Poly bd® and Krasol® hydroxyl-terminated polybutadienes comply with title 21 (Food and Drugs) of the Code of Federal Regulations, paragraph 175.300, Resinous and Polymeric Coatings. Cray Valley Company is also supplying non-hydroxyl terminated derivatives of the Poly bd® and Krasol® resins. These include isocyanate (MDI or TDI) terminated prepolymers (Krasol® NN and Krasol® LBD), acrylate-terminated and carboxyl-terminated resins. These products provide the same general properties as the hydroxyl-terminated resins but with more curing and crosslinking options. Poly bd® and Krasol® resins are used in various industries including construction, automotive, electronics and rubber. They are incorporated in castable elastomers, caulks, sealants, waterproof membranes, foams, adhesives, coatings, binders for composites, potting and encapsulation compounds as well as other rubber- fabricated materials. 4 Functionalized Polybutadiene Resins Currently Offered by Cray Valley Company The tables below summarize the functionalized poly- Valley Company.

Newkome ______________________________ Committee Member Dr. Wayne L. Mattice ______________________________ Committee Member Dr. Peter L. Rinaldi i i ABSTRACT 2,3,4,5,6-Pentafluorostyrene (PFS) was polymerized in the presence of a solution of polybutadiene (PB) in tetrahydrofuran using benzoyl peroxide as the radical initiator at 50, 60, 80 ºC. The products were graft copolymers of poly(2,3,4,5,6-pentafluorostyrene) (PPFS) into PB. The copolymerizations follow typical free radical polymerization kinetics and behavior, with the rate of propagation proportional to the monomer concentration and the square root of the initiator concentration. Gel permeation chromatography (GPC) equipped with two detectors (UV and refractive index) has allowed us to determine conversion of the monomer, graft efficiency, graft ratio and graft frequency of the grafted products obtained at different temperatures and initiator concentrations, without the need of purification and/or isolation of the final graft copolymer. Conversion of the monomer and graft ratio increase and grafting frequency decreases with increasing temperature and initiator concentration.

  • Improvement of Devulcanization Yield During Reclamation Ofwaste Tires
    Global Journal of Researches in Engineering Chemical Engineering Volume 13 Issue 1 Version 1.0 Year 2013 Type: Double Blind Peer Reviewed International Research Journal Publisher: Global Journals Inc. (USA) Online ISSN: 2249-4596 & Print ISSN: 0975-5861 Improvement of Devulcanization Yield during Reclamation of Waste Tires By Dr. Kalrenganathan Sharma Lone Star College University Park Abstract - Waste tire recycling has become a bigger environmental problem. Despite regulations waste tires are stockpiled and often are breeding ground for west Nile virus and mosquitoes that cause pandemic. A number of times waste tires are incinerated or pyrolysis. Reclamation of value in the rubber portion of the waste tires may be more profitable and more environmentally benign compared with incineration and fuel use methods. Devulcanization and depolymerization reactions can lead to recovery of polybutadiene and butadiene monomer. Competing parallel reactions after the devulcanization step is studied in more detail. Dynamics of the general Denbigh scheme of reactions in a CSTR is studied. The composition of the species involved is obtained as a function of time from model solutions. A general state space form is proposed for simultaneous series-parallel reactions. Types of instability that may arise depends on the eigenvalues of the system. The Eigenvalues of the sparse matrix indicate that the system is of the integrating type. Solutions can be obtained from the eigenvalues for 7 species. Information from the model solution can be used to optimize the yield of rubber during reclamation of rubber from waste tires.

  • Polybutadiene Rubber (PBR) Is a Synthetic Rubber. PBR Is Produced by the Polymerization of 1,3-Butadiene
    Polybutadiene rubber (PBR) is a synthetic rubber. PBR is produced by the polymerization of 1,3-butadiene. PBR has a high resistance to abrasion and is mostly used in the manufacture of tires. About 75% of the production of this material is consumed in the rubber industry. Another 25% is used as an additive to improve the toughness (impact resistance) of plastics such as High-Impact Polystyrene (HIPS) and Acrylonitrile-Butadiene-Styrene (ABS). PBR accounts for about a quarter of the total global consumption of synthetic rubbers. The PBR is produced by the following reaction: High-cis polybutadiene Low-cis polybutadiene High-vinyl polybutadiene High-trans polybutadiene www.rayeneh.com Low-cis polybutadiene is used for producing of high-impact polystyrene, but high-cis is used in tires, shoes, car parts and golf balls. In the low-cis type, the cis percentage should not exceed 35% by weight, but in the high-cis type, it should be more than 95% by weight. The catalyst used determines the type of produced polybutadiene rubber. PBR is supplied in bale weight (35 kg) or in box weight (1050 kg). These packages should be stored in cool, dry warehouses away from heat sources and other chemicals. The storage temperature of these materials should not exceed 30° C. It should be noted that the remnants of this polymer composition should not be discharged into streams and sewage under any circumstances. Rayenehdaran Company is fully prepared to supply the PBR continuously and just in time delivery at a competitive price. Rayeneh Group is an international supplier of chemicals, catalysts, and equipment in the Oil, Gas, Petrochemical, and Mine Industries.

  • 7: Source-Based Nomenclature for Copolymers (1985)
    7: Source-Based Nomenclature for Copolymers (1985) PREAMBLE Copolymers have gained considerable importance both in scientific research and in industrial applications. A consistent and clearly defined system for naming these polymers would, therefore, be of great utility. The nomenclature proposals presented here are intended to serve this purpose by setting forth a system for designating the types of monomeric-unit sequence arrangements in copolymer molecules. In principle, a comprehensive structure-based system of naming copolymers would be desirable. However, such a system presupposes a knowledge of the structural identity of all the constitutional units as well as their sequential arrangements within the polymer molecules; this information is rarely available for the synthetic polymers encountered in practice. For this reason, the proposals presented in this Report embody an essentially source-based nomenclature system. Application of this system should not discourage the use of structure-based nomenclature whenever the copolymer structure is fully known and is amenable to treatment by the rules for single-strand polymers [1, 2]. Further, an attempt has been made to maintain consistency, as far as possible, with the abbreviated nomenclature of synthetic polypeptides published by the IUPAC-IUB Commission on Biochemical Nomenclature [3]. It is intended that the present nomenclature system supersede the previous recommendations published in 1952 [4]. BASIC CONCEPT The nomenclature system presented here is designed for copolymers. By definition, copolymers are polymers that are derived from more than one species of monomer [5]. Various classes of copolymers are discussed, which are based on the characteristic sequence arrangements of the monomeric units within the copolymer molecules.

  • The Effects of Heat Aging on Acrylonitrile-Butadiene
    THE EFFECTS OF HEAT AGING ON ACRYLONITRILE–BUTADIENE– STYRENE (ABS) BLENDS Heat aging of ABS blends B.E. TIGANIS and L.S. BURN CSIRO Building, Construction and Engineering, Victoria, Australia Durability of Building Materials and Components 8. (1999) Edited by M.A. Lacasse and D.J. Vanier. Institute for Research in Construction, Ottawa ON, K1A 0R6, Canada, pp. 912-922. Ó National Research Council Canada 1999 Abstract Degradation of thick ABS materials at elevated temperatures is observed to be predominantly a surface effect which deteriorates the bulk mechanical properties under impact conditions. It is postulated that a critical level of surface degradation initiates polymer crazing in the rubbery butadiene phase, which propagates through the polymer, causing failure. A physico-mechanical study of the effects of heat aging on the rubbery phase in ABS reveals an increase in the loss modulus and tan d, demonstrating a decrease in the free volume which may be due to cross-linking of free radicals formed by hydrogen abstraction and chain scission. Microscope FTIR spectroscopy of aged ABS surfaces shows that the degree of butadiene unsaturation decreases with time, and that carbonyl and hydroxyl absorbances increase as expected with thermo-oxidative degradation. Degradation of the rubbery polybutadiene phase in ABS may be initiated by hydrogen abstraction from the carbon a to unsaturated bonds, producing hydroperoxide radicals leading to carbonyl and hydroxyl products. Cross-linking is facilitated by the free radicals produced. Heat aging of ABS at elevated temperatures below the glass transition (Tg) of the SAN phase causes physical aging. This aging of the SAN phase provides thermal energy which allows for a structural reconfiguration of the glassy morphology towards an amorphous polymer.

  • Impact Behaviour of Acrylonitrile-Butadiene-Styrene After Temperature and Humidity Load
    MATEC Web of Conferences 125, 02048 (2017) DOI: 10.1051/ matecconf/201712502048 CSCC 2017 Impact behaviour of acrylonitrile-butadiene-styrene after temperature and humidity load Lenka Hylova 1,*, Miroslav Manas1 1Tomas Bata University in Zlin, nam. T. G. Masaryka 5555, 76001 Zlin, Czech Republic Abstract. This study deals with acrylonitrile-butadiene-styrene (ABS) which was subjected the drop-weight test before and after temperature and humidity load. ABS is an engineering plastic and also an important engineering terpolymer, which has butadiene part uniformly distributed through the acrylonitrile-styrene matrix and is commonly used in production of automotive interior components. The injection moulded ABS samples were subjected the penetration test at fall height 100 J before and after temperature and humidity load and the results were subsequently evaluated and discussed. It was found out that ABS after temperature and humidity load has lower impact resistance. 1 Introduction construction, computer and business equipment, personal care products, toys, medical devices and in automotive Acrylonitrile-butadiene-styrene (ABS) is an engineering interior components [1-3]. plastic and also an important engineering terpolymer, Brazilian scientists investigated three types of which has butadiene part uniformly distributed through commercial ABS, namely GP (ABS for general-purpose the acrylonitrile-styrene matrix. ABS was use), HI (an ABS high impact) and HH (ABS high heat commercialized at the latter of 1940s by U.S. Rubber and resistance). They studied activation energy of all three originally was made by blending of polystyrene-co- ABS and they realized that it is much higher than acrylonitrile (SAN) and NBR acrylonitrile-butadiene reported in the literature.
