Abstract

A structural-morphological study of radiation-grafted copolymers of PE with PAA has been carried out. It was shown that as well as the permeation of the PAA into the polymer, an increase in the PAA concentration in the grafted phase occurs, the rate of the subsequent process being about 1·5 times greater than that of the first one. Under given conditions, the process rate is not diffusion-controlled. It was shown that grafting is accompanied by breakdown of the para-crystalline structure of the PE. The conditions for complete covering of the PE surface with a grafted layer have been established.
