摘要
利用聚丙烯等离子体接枝甲基丙烯酸甲酯共聚物（ＰＰ－ｇ－ＰＭＭＡ）作增容剂，研究了其在聚丙烯／聚偏氟乙烯（ＰＶＤＦ）共混体系中的作用。增容是通过ＰＭＭＡ与ＰＶＤＦ的偶极－偶极相互作用实现的。接枝共聚物使共混体系的抗张强度和模量均有提高，由不同等离子体处理时间所得的ＰＰ－ｇ－ＰＭＭＡ，接枝率在７．７％～３００％具有最好的增容效果；而由不同后聚合时间所得的共聚物，接枝率在３０％～８０％具有最好的增容效果。
Plasma-induced graft copolymers of methyl methacrylate onto polypropylene (PP-g-PMMAI were used as compatilizers in the blend system of PP and polyvinylidene fluoride (PVDF).SEM and FTIR showed that it was the dipole-dipole interaction between the fluorine of PVDF and the carbonyl of PMMA of the compatilizer that made the polymers compatible. Mechanical property studies of the blend system showed that PP-g-PMMA copolymers with grafting yields of 7.7%￣300% from various plasma treatment time or of 30%￣80% from different post-polymerization time had the best compatibility effect.
