POE在塑料改性中的应用进展

PROGRESS IN THE APPLICATION OF POE IN THE MODIFICATION OF PLASTICS

综述近几年聚烯烃弹性体(POE)与通用塑料、工程塑料共混改性的进展。与改性剂(乙烯/丙烯/二烯)共聚物和(苯乙烯/乙烯-丁烯/苯乙烯)共聚物相比,POE和功能化的POE作为一种新型改性剂能在较低含量下实现材料的脆-韧转变,减少了因加入弹性体造成的材料强度和模量的损失。

The progress in the modification of general-purpose plastics and engineering plastics, with POE as modifier, is reviewed. As a kind of novel modifier, compared with EPDM and SEBS modifiers, the brittle-ductile transition of materials can be achieved in the lower content of POE and the functionalized POE,and the loss of strength and modulus caused by the addition of the elastomer can be decreased.
