This article shows the feasibility of using EVA as blending modifier on the basis of studying the molecular weight of PE, and its distribution, the structure of molecular chain and the influence on ESCR by PE and the morphology of other blending polymer.

• 本文在研究PE分子量及其分布、分子链结构以及PE与其它高聚物的共混物形态结构对ESCR影响的基础上,指出采用EVA作共混改性剂的可行性;
