摘要

本文研究辐照PP/HDPE共混物的溶胶生成分数s与辐照剂量R的关系

结果表明适用于某些纯聚合物辐射交联规律的Charlesby-Pinner关系式和陈-刘-唐关系式皆不适用于PP/HDPE共混体系。张万喜等人曾研究过许多纯聚合物的辐射交联

提出裂解度正比于Rβ的假定

β是与高分子结构相关的参数

这个假定可与大多数聚合物的辐射交联实验数据符合。同样的假定被应用于本文的共混体系

不同的是根据共混物结构特点对Rβ项进行了必要的修正

即共混物的Rβ=∑fiRβI

其中fi

βi分别为共混物第i组分的重量分数及β值。用修正后的Rβ处理辐照PP/HDPE共混物的实验数据

R(s+√s)～Rβ

有很好的线性关系。

Abstract

In the present work

the relationship between sol fraction (s) and radiation dose (R) in radiation crosslinking of PP/HDPE blends was studied. The results indicate that both Charles-by-pinner expression and Chen-Liu-Tang expression

which were well applicable with radiation crosslinking of some polymers

do not well fit to the case of PP/HDPE blends.According to Zhang's assumption

which deals with relationship between structure and radiation crosslinking of pure polymers and applies to most cases

fracture density of polymer is proportional to Rβ

where β is a parameter depending on the structure of a polymer.In this paper

we extended their assumption to polymer blends

but the Rβ value of blends were modified by equation Rβ=∑fiRβi

where fi and βi are weight fraction and β value of i component in blend

respectively. Using the modified Rβ

good linear relation between R(s+s)and Rβ of PP/HDPE blends was obtained.
