摘要

聚丙烯是目前应用最广泛的通用塑料之一

在国民经济和日常生活中发挥了重要作用。作为半结晶材料

聚丙烯及其合金的性能很大程度上取决于微观结构

包括晶型、结晶度、取向、相形态和尺寸等。本文综述了课题组近年来在聚丙烯及其共混物的结构和性能研究方面的进展

包括聚丙烯/成核剂、聚丙烯釜内合金、聚丙烯/弹性体共混物

以及聚丙烯/刚性粒子复合物等。针对我国聚丙烯树脂产能快速增长但高端聚丙烯树脂缺乏的突出矛盾

深入开展聚丙烯基础结构和性能关系的研究仍具有十分重要的意义。

Abstract

As one of the most broadly applied general plastics

polypropylene (PP) has played a significant role in the economy and everyone’s daily life. The performance of PP and its blends are determined largely by the microstructure and morphology

including the crystal type

crystallinity

orientation

phase morphology. We summarized the research advances in our group regarding the structure and property relationship of PP and its blends. The topics cover the PP/ nucleating agents

PP in-reactor alloys

PP/elastomer blends

and PP/rigid particle compounds. There is a clear mismatch between the rapid growth in productivity of PP general grade resins and the shortage of high-end PP resins. It is essential to continue the study of the basic structure and properties relationship of PP materials.
