| 摘 要： | 在两种不相容的聚合物组成的共混体系中加入增容剂，可以显著提高共混体系的力学性能．目前的理论解释是嵌段共聚物在不相容的聚合物间形成界面层，通过降低组分间的界面张力、增强界面粘接力达到增容目的［‘－‘1．但是这一假设缺乏直接的实验证据．本文利用透射电子显微镜，

| Abstract: | The influence of poly(styrene-b-methyl methacrylate) on the interface of PVC/SBSblends is studied by TEM and DMA, When only two pwrcent of PS-b-PMMA is added to PVC/SBS(100/15) blends ,the thickness of the interface get thickened obviously, The molecular weight and the composition of PMMA blocks and PS bolcks have important influence on theinterface of PVC/SBS blends. |
