摘要

该文采用负载型β-成核剂成核PP分别与PS、AS、ABS共混制备了β-PP共混物。用DSC和WAXD研究了苯乙烯系聚合物对β-成核PP中的β-成核作用的影响和β-PP共混物的结晶行为、结晶形态、熔融特性和β-晶含量。观察到随着苯乙烯系聚合物用量增加，β-成核PP的结晶温度稍有降低，尤其ABS。苯乙烯系聚合物加入不影响β-成核PP的熔融特性，呈现三个熔融峰。β-成核PP共混物的β-晶含量随着苯乙烯系聚合物用量增加而降低，但可得到β-晶含量高于80%以上β-PP共混物。

Abstract

β-Polypropylene (PP) blends were prepared with supported β-nucleator nucleated PP and PS

ABS

respectively. The β-nucleation

crystallization behavior

melting characteristic and β-crystal content were investigated by DSC and WAXD. It was observed that the crystallization temperatures of β-nucleated PP slightly decreased with increasing styrenic polymers content

especially ABS. Addition of styrenic polymers had no influence on melting characteristic of β-nucleated PP， and three melting peaks were observed. Although the content of β-crystal in β-nucleated PP blends slightly decreased with increasing styrenic polymers content

β-PP blends were obtained with β-crystal content above 80%.
