摘　　要：研究了滑石粉、聚烯烃弹性体(POE)对回收聚丙烯收缩率及结晶行为的影响。结果表明,滑石粉可以明显降低回收聚丙烯的收缩率,但对不同类型回料复配体系影响更为显著;POE通过改变回收聚丙烯的结晶行为可以降低收缩率,其中乙烯-辛烯弹性体比乙烯-丁烯弹性体对回收聚丙烯结晶度影响更大,表现出更低的收缩率。The effects of talc and polyolefin elastomer （ POE） on shrinkage and crystallization behavior of recy-cled polypropylene （ PP） were researched. The results showed that talc can decrease remarkably shrinkage of recy-cled PP and talc has a more significant influence on shrinkage for the blends of different type recycled PP. POE can also decrease shrinkage of recycled PP by means of changing crystallization behavior of recycled PP. Ethylene-oc-tene elastomer has a more influence on shrinkage than Ethylene-butene elastomer and recycled PP with ethylene-oc-tene elastomer has a lower shrinkage.
