| 摘 要： | 采用机械共混、化学交联工艺制备高聚合度聚氯乙烯(HMWPVC)/聚甲醛(POM)/丁腈橡胶(NBR)三元共混弹性体合金。重点讨论了HMWPVC/POM/NBR共混比、PVC树脂的相对分子质量、NBR橡胶的丙烯腈含量、硫化体系等因素对弹性体性能的影响。HMWPVC/POM/NBR共混弹性体的力学性能、耐油耐溶剂性能优于PVC/POM/NBR共混弹性体。采用动态粘弹谱仪、扫描电子显微镜等现代分析技术研究了HMWPVC/POM/NBR三元共混弹性体的微观结构，结果显示HMWPVC/POM/NBR(10/10/80)三元共混弹性体的tgδ－T谱上只出现一个峰值，其对应的玻璃化转变温度为－0.8℃，三元共混弹性体具有较好的相容性。

| 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℃. |
