摘要
采用氢化聚丁二烯－ｂ－甲基丙烯酸甲酯（ＰＢＤ－ｂ－ＰＭＭＡ）共聚物作为聚氯乙烯／线性低密度聚乙烯（ＰＶＣ／ＬＬＤＰＥ）共混体系的增容剂，用扫描电子显微镜（ＳＥＭ）和透射电子显微镜（ＴＥＭ）对共混体系的冲击缺口断面和相结构进行了研究。并用小角激光散射技术研究了ＬＬＤＰＥ在共混物中的结晶行为，发现增容剂对共混体系的形态结构会产生极大的影响。
Hydrogenation poly(butadiene-b-methyl methacrylate)copolymer had been used as compatibilizer for PVC/LLDPE blends.The results obtained from SEM and TEM show that the compatibilizer play an important role in the control of morphologies for PE/LLDPE blends.the SALS technology was also used to understand the crystalline process of LLDPE in PVC/LLDPE blends and to study the effects of copolymer on compatibility of blends.
