摘要

本文主要介绍以电子加速器的高剂量率电子射线合成水凝胶材料的研究

主要结果如下: 1.在动力学进程中

当转化率约20％时才产生凝胶。完成动力学进程所需辐照剂量只需0.5—2.0×10~0rad

辐照时间为1—4分钟; 2.聚合初速率(V_0)与剂最率(Ⅰ)的关系如下:HEMA+EGDMA体系:V_0∞I~(0.53); HEMA+IOMA+EGDMA体系:V_0∞I~(0.48); HEMA+IOAM+EGDMA+RH体系:V_0∞I~(0.50); 3.在聚合物链中引入疏水性单体

可以大大改善水凝胶材料的强度

但含水量相应降低。 4.本材料已用于超薄型软接触镜的生产。

Abstract

This paper presents a study on synthesis of a hydrogel material hy high dose rate electron beam produced by accelerator. The main results are as follows:1. The polymerization system produces the gel when the conversion attains approximately 20%.The radiation doae which completes this kinetic process is only 0.5-2.0Mrad

in other words

the radition time requires only 1-4min.2. The relationship between the initial rate of polymerization (V) and dose rate (I) are as follows:HEMA+EGDMA system: V_0∞I~(0.53) HEMA +EHMA+EGDMA system: V_0∞I~(0.48) HEMA+ EHMA+ EGDMA + RH system: V-0∞I~(0.5)3. When the compounding includes the hydrophobie monomer such as butyl acrylate

the mechanical strength of soft lens made from the hydrogel material is increased while the water absorption is decreased.4. The hydrogel material have been used for the manufacture of the soft contact lenses.
