摘要
基于Ziegler-Natta催化剂进行丙烯多相共聚是制备聚丙烯多相共聚物的主要方法之一，由于线性乙丙橡胶(EPR)极易发生流动会影响聚合物的颗粒形态和橡胶相的相形态，因此，本文通过在聚合中引入氯硅烷功能化非共轭
α
ω
-双烯烃，使其参与乙丙无规共聚并使EPR发生同步交联，以解决上述问题. 结果显示，氯硅烷功能化非共轭
α
ω
-双烯烃引入后EPR分子链之间形成交联结构，有效抑制了EPR液滴的流动和聚集，使聚合物具有良好的颗粒形态，EPR相以较小的相畴尺寸均匀地分散在PP基体中，而且硅氯基团遇水发生缩合反应可进一步提高支化/交联效率，进一步稳定聚合物的相形态，聚合物的力学性能得到较大的提升.
Abstract
Heterophasic copolymerization of propylene based on Ziegler-Natta catalyst is one of the major methods for preparing polypropylene/ethylene propylene rubber (PP/EPR) heterophasic copolymer. Compared with traditional physical blending method
PP/EPR heterophasic copolymer can achieve even dispersion of EPR phase in PP matrix with smaller phase domain size. However
for linear EPR
it is prone to flow and aggregate during polymerization
resulting in adhesion between/among polymer particles. In addition
the PP/EPR heterophasic copolymer will undergo significant phase separation during melt processing
and the EPR droplets will aggregate into larger rubber particles. Moreover
the longer the melting processing time
the more serious the phase separation of PP phase and EPR phase
and the larger the size of rubber particles. Therefore
it is very important to control the particle morphology and EPR phase morphology of propylene heterophasic copolymer. In this study
a dichlorosilane functionalized nonconjugated
α
ω
-diolefin
di(5-hexenyl)dichlorosilane
was introduced into the polymerization and participated in the random copolymerization of ethylene/propylene to prompt cross-linking of EPR. The results showed that the dichlorosilane functionalized nonconjugated
α
ω
-diolefin rendered the formation of cross-linked EPR
and the flow and aggregation of EPR droplets were effectively controlled. The surface morphology of PP/EPR copolymer particles was observed by SEM
which showed that all samples had good particle morphology. TEM and AFM results showed that EPR was evenly dispersed in the PP matrix with a small phase domain size. Moreover
the condensation reaction of the Si―Cl group in the presence of water further enhanced the branching/cross-linking of the copolymer
which led to a greater extent stabilized the phase morphology of the copolymer. As a result
the mechanical properties of PP/EPR copolymer were greatly improved.
