摘要

本文用电子加速器的电子射线研究了凝胶化剂量(R_g)之前辐照EVA时

辐照条件对其加工性能和物理机械性能的影响在R_g之前辐照EVA

不产生凝胶而降低M.I.

改善了EVA的加工性能和物理机械性能.随辐照剂量的增加

EVA的M.I.递减规律是:R≤1.7× 10~5(M.I.)_O~(0.23)时.M.I.=11.2R~(-0.21)(M.I.)0;R≥1.7×10~5(M.I.)_0~(0.23)时

M.I.=4.9×10~(11)R~(-2.25)(M.I)_0~(1.44)X-射线衍射图及红外谱图表明

在本试验范围内

EVA辐照前后的序态结构及化学结构均无明显变化.

Abstract

The effect of irradiating EVA with electron beam

at less than the gel dosage(R8)

on processability and mechanical properties has been investigated. Under such mild radiation

gel was not produced and the M. I. decreased so that both processability and mechanical properties was improved. With increase in radiation dosage

the M. I. of EVA decreases according to the following relations: Both x-ray diffraction and infra-red absorption spectrum showed that in the present experiments both the order structure and constitution of EVA

before and after irradiation

remained essentially the same.
