摘要

借γ射线预照射法将丙烯腈接枝到高取向的聚丙烯上。获得了该接枝共聚物的X射线衍射图

比较了接枝后取向和取向后接枝的差别

指出取向后接枝系统处于准稳定态

有利固定高分子的取向。

Abstract

The structure of graft copolymer has been investigated by X-ray diagrams. The grafting process was carried out through prelin inary irradiation of oriented polypropylene with gamma-radiation and then treated with acrylonitrile.With the aid of X-ray diagrams

a model for the state of molecular aggregation of the copolymer under investigation was suggested. It was found that shrinkage of the said copolymer is smaller than that of oriented polypropylene and that of the oriented graft copolymer made from acrylotrile and polypropylene. The present graft system is in a quasi-stable stat which fixes the molecular orientation in the polymer.
