摘要

本文通过种子乳液聚合合成了一种新型的基于MAP-POSS的纳米丙烯腈-苯乙烯-丙烯酸酯共聚物#(POSS-ASA)

然后制备PVC/POSS-ASA纳米复合材料。研究了PVC/POSS-ASA 的塑性行为和流变行为

讨论了组成对PVC/POSS-ASA熔体的平衡扭矩、塑化时间和非牛顿指数(n)的影响

确定了动态力学性能、机械性能和形态。结果表明

随着POSS-ASA 含量的增加

塑化时间缩短

熔体粘度增加。共混物的储能模量也随着POSS-ASA含量的增加而降低。当POSS-ASA 含量仅为1%(wt)时

抗冲击强度和拉伸强度分别比纯PVC高3.3kJ/m

和12.2MPa。POSS-ASA可用作PVC的有效抗冲助剂和加工助剂。

Abstract

In this work

a novel nanometer acrylonitrile-styrene-acrylate co-polymer based on MAP-POSS (POSS-ASA) was synthesized via seed emulsion polymerization

then the PVC/POSS-ASA nanocomposite were prepared. The plastic behavior and rheological behavior of PVC-POSS-ASA were investigated. The influences of composition on balance torque

plastic time

and non-Newtonian index (n) of PVC-POSS-ASA melts were discussed. The dynamic mechanical properties

mechanical properties

and morphology were determined. The results showed that the plastic time decreased but melt viscosity increased with increasing POSS-ASA content. The storage modulus of blend also decreased with increasing POSSASA content. When POSS-ASA content was only 1%(wt)

the impact strength and tensile strength was 3.3kJ/m

and 12.2MPa higher than that of pure PVC

respectively. POSS-ASA can be used as an efficient impact aid and process aid for PVC.
