摘要

研究了聚乙烯（PE）与丙烯酸（AA）、甲基丙烯酸（MAA）的接枝共聚反应，探讨了接枝反应过程及特征：单体首先在PE表面接枝，然后进入内部进行本体接枝。研究表明：表面接枝为动力学控制；本体接技系扩散控制，单体在膜内的扩散与单体极性及聚合物的结晶度等有关。

Abstract

Direct radiation grafting of acrylic acid (AA) and methacrylic acid (MAA) onto polyethylene (PE) films were studied. The investigation of the nature and characters of grafting proceeding were performed. The penetration of grafting onto the thin PE film was studied and the mechanism discussed. This involevs an initial stage whereby the grafted surface layer deforms the PE allowing further monomer to penetrate. It was shown that the surface grafting was dynamic controlled and the penetration of monomer depended on the polarity of monomer.
