  • Studies on Radiation Crosslinking of Polysulfone
    JP0050427 JAERI-Conf 2000-001 Studies on Radiation Crosslinking of Polysulfone Xiaoguang Zhong Jiazhen Sun Changchun Institute of Applied Chemistry Chinese Academy of Sciences Changchun 130022, China Polysulfone is a kind of high temperature-resistance and radiation-resistance engineering plastic. The chemical structure is as follows: Brown (1), Lyon (2), Sasuga (3), et al have already studied its radiation effect. We studied CH3 radiation crosslinking effect of polysulfone by using of XPS, ESR, and CG methods and got some new results. Results and Discussions 1. Study radiation crosslinking of polysulfone by XPS method Because of conjugate system of benzene ring, polymer material which contains of benzene ring will appear shake-up peak in XPS spectra. Wanxi Zhang (4) shows that during radiation crosslinking of polystyrene increases with radiation dose and the intensity of shake-up peak decreases gradually with increase of radiation dose and crosslinking degree. This suggests that radiation crosslinking destroyed conjugate system of benzene ring. During radiation crosslinking of polysulfone, we find rules of shake-up peaks in the XPS spectra are different at different radiation crosslinking temperature. At lower temperature the intensity of shake-up peak decreases with the increase of radiation dose. This rule is similar to that of radiation crosslinking of polystyrene. The results are shown in Fig. 1. 183- JAERI-Conf 2000-001 Fig. 1. The spectra of radiation crosslinking of polysulfone at 70"C Comparing with radiation crosslinking at lower temperature, the intensity of shake-up peak increases with radiation dose when radiation crosslinking reaction takes place at temperature above glass transition temperature of polysulfone.

  • High Performance Reactive Blends Composed of Poly(P-Phenylene Sulfide)
    Polymer Journal (2011) 43, 991–999 & The Society of Polymer Science, Japan (SPSJ) All rights reserved 0032-3896/11 $32.00 www.nature.com/pj ORIGINAL ARTICLE High performance reactive blends composed of poly(p-phenylene sulfide) and ethylene copolymers Hideko T Oyama, Mayu Matsushita and Motonobu Furuta Poly(p-phenylene sulfide) (PPS) is a high performance polymer that has superior chemical resistance and heat stability, but its brittleness is a serious drawback for applications. The objective of this work is to improve the physical properties of PPS by incorporating a small amount of either poly(ethylene-ran-methylacrylate–ran-glycidyl methacrylate) (EMA–GMA) or poly(ethylene- ran-glycidyl methacrylate)-graft-poly(methyl methacrylate) (EGMA-g-PMMA) by melt mixing under a high shear rate. It was demonstrated that the chemical reaction between PPS and EMA–GMA (or EGMA-g-PMMA) proceeded efficiently at the interface and that the domains of EMA–GMA (or EGMA-g-PMMA) were finely dispersed in the PSS matrix with size of ca 0.1–0.3 lm. The resultant copolymers formed at the interface contributed to a decrease in the interfacial tension and an increase in the interfacial adhesion so that the obtained PPS/EMA–GMA blends (or PPS/EGMA-g-PMMA blends) showed excellent mechanical properties, at the same time retaining high thermal stability. Polymer Journal (2011) 43, 991–999; doi:10.1038/pj.2011.106; published online 19 October 2011 Keywords: blend; copolymer; interface; poly(ethylene-ran-glycidyl methacrylate); poly(phenylene sulfide) INTRODUCTION ties are not reported in the same paper, it was found that the Poly(phenylene sulfide) (PPS) is a high performance super-engineer- activation energy of crystallization of PPS increases by blending ing plastic with high thermal stability (over 150 1C), excellent chemical with PES and that the equilibrium melting temperature decreases resistance (no solvents under 200 1C), good electrical and electronic linearly with increase of the PES content.
