Implementing NIR for Polymer Production Process Monitoring Dr
Implementing NIR for Polymer Production Process Monitoring Dr. Hari Narayanan, Senior Product Manager – Spectroscopy, Metrohm USA Inc Introduction while at the bench or pilot plant level it can be used to Polymers are a very important class of organic materials, optimize reaction conditions. Finally, when used in a widely used in many fields due to their unique properties complete feedback-control-loop at the industrial reactor such as tensile strength and viscoelastic behavior under level, significant improvement in product quality can be deformation. With more stringent demands on the quality expected, as well as savings of non-renewable resources, of polymer products and pressure to reduce cost in energy, reactor and personnel time. Creating an effective production and processing, the need for fast, accurate and NIR implementation strategy depends on the type of reliable monitoring methods is greater than ever. polymerization process, the properties of interest, and measurement conditions. Analytical methods, which require time-consuming and intensive sample preparation, are difficult to implement Polymerization Processes effectively in a process or quality control environment, NIR spectroscopy can be used for bulk, solution, emulsion and waste precious time and materials. Efficient process and suspension polymerization monitoring, providing control demands a measurement technique which is information on copolymer composition and distribution, rapid, requires little or no sample preparation and minimal monomer conversion, molecular weight averages, average technical expertise. It should be reliable, rugged and easily particle sizes and more. automated. Bulk polymerization Near-infrared (NIR) spectroscopy meets those needs by In bulk polymerization, the reaction is carried out in the being both rapid and precise. -

Even though FCS has been mainly applied to biological systems, within the last 15 years an increasing number of studies in material sciences have appeared, demonstrating its enormous potential also for this field. Apart from investigations on colloidal systems, polymer science has benefited significantly from this technique. This review will summarize FCS studies on polymer systems and, in particular, focus on the diffusion of differently sized molecular and macromolecular probes in polymer solutions, classical and responsive polymer gels, polymer melts and glasses. It will be discussed how FCS can be used to determine Received 5th September 2013 translational and rotational diffusion in polymer solutions and at interfaces, scaling laws, micellization Accepted 5th November 2013 and aggregation and, to some extent, polymer structure including heterogeneity.

CARBOHYDRATE POLYMERS a Journal Devoted to Scientific and Technological Aspects of Industrially Relevant Polysaccharides
CARBOHYDRATE POLYMERS A Journal Devoted to Scientific and Technological Aspects of Industrially Relevant Polysaccharides AUTHOR INFORMATION PACK TABLE OF CONTENTS XXX . • Description p.1 • Audience p.2 • Impact Factor p.2 • Abstracting and Indexing p.2 • Editorial Board p.2 • Guide for Authors p.6 ISSN: 0144-8617 DESCRIPTION . Carbohydrate Polymers is a major journal within the field of glycoscience, and covers the study and exploitation of polysaccharides which have current or potential application in areas such as bioenergy, bioplastics, biomaterials, biorefining, chemistry, drug delivery, food, health, nanotechnology, packaging, paper, pharmaceuticals, medicine, oil recovery, textiles, tissue engineering and wood, and other aspects of glycoscience. The role of the well-characterized carbohydrate polymer must be the major proportion of the work reported, not a peripheral topic. At least one named carbohydrate polymer must be cited and be the main focus of the paper and its title. Research must be innovative and advance scientific knowledge. Characterization - For all polysaccharides, including those obtained from a supplier, essential structural information which will affect their behavior in the subsequent work should be given, along with a description of how that information was ascertained. Examples of such essential information include molecular weight, mannuronate/guluronate ratio for alginates, degree of esterification for pectin, degree of deacetylation for chitosan. Editors are unlikely to send papers for formal review with a statement such as "sodium alginate was purchased from XXX Inc." unless additional information is supplied. For papers involving synthesis, polysaccharide derivatives must also be well- characterized. For papers describing identity or application of newly-discovered polysaccharides, purity and monosaccharide composition are essential; some molecular size and linkage information is highly desirable. -
