PVC/ACR共混物相分离、相溶解行为研究

STUDIES OF THE BEHAVIORS OF PHASE SEPARATION AND PHASE DISSOLUTION OF BLENDS POLYVINYL CHLORIDE (PVC)WITH ACRYLATE ELASTOMER (ACR)

本文用激光散射技术研究具有特殊核壳结构的丙烯酸酯类弹性体(ACR)等改性剂与聚氯乙烯(PVC)共混物的相分离行为,得到了它们的相界图,并讨论分子量、分子量分布的影响,还对相溶解行为进行了初步探索。

In this paper, by using laser scattering technique, we investigated the behaviors of phase separation of blends of PVC and poly-(methyl methacrylate-co-butyl acrylate) which possessed special shell structure, obtained their phase boundary diagrams and discussed effect of molecular weight and distribution of molecular weight to it. Furthermore, we also studied phase dissolution of blends PVC/ ACR.
