摘　　要：流变研究发现,mPE/LDPE交联物具有多分散性的蜂窝状网络结构,并呈现类弹性体特征。在嵌段共聚聚丙烯的增容下,可以显著提高均聚聚丙烯的冲击韧性,且其耐高温蠕变性能也优于几种典型的聚丙烯管材专用料。Rheological study showed that the mPE/LDPE crosslinked complexes could perform obvious polydispersity with Honeycomb-like network microstructures and demonstrate some elastomer-like characteristics. The impact strength of homo polypropylene could be significantly enhanced by this kind of mPE/LDPE crosslinked complexes at the presence of block polypropylene as its compatibilizer. The creep property of this composite at high temperatures also exceeds classic special resin for pipe production.
