高聚合度聚氯乙烯/聚甲醛/丁腈橡胶三元共混弹性体的研究
STUDY ON HMWPVC/POM/NBR TERNARY BLENDING ELASTOMERS
摘要
Abstract
Ternary blending elastomers comprised of high degree polymerizaed PVC(HMWPVC), polyformaldehyde(POM) and acrylonitrile-butadiene rubber(NBR) were prepared by the process of mechanical blending at high temperature and chemical crosslinking. The effects of blending ratio of HMWPVC/POM/NBR, average degrees of polymerization(\{DP\}) of polyvinyl chloride resins, types of NBR rubbers and curing systems on the properties of ternary blending elastomer were discussed. The ternary blending elastomer of HMWPVC/POM/NBR had better physical mechanical properties, oil and solvent resistance than that of the ternary blending elastomer of PVC/POM/NBR. The experiment data of scanning electron microscope and dynamic mechanical analysis showed that the ternary blends had better compatibility. The glass transition temperature of the ternary blending elastomer of HMWPVC/POM/NBR(10/10/80,by wt.) was -0.8℃.关键词
