摘要: 聚合物辐射交联和裂解的动力学分析结果表明,交联并不是严格地与剂量成正比。特别是在辐照初期很低剂量范围内,分子量异常地下降.辐照聚对苯二甲酸二醇酯的粘度测定支持了这一理论结果.

关键词: 聚酯, 辐射效应, 交联和裂解

Abstract: The result of the analysis on the kinetics of cross-linking and scission of polymers subjected to irradiation states that the cross-linking is not directly proportional to the dose, especially in the early stage of irradiation.So a rapid drop of molecular weight should be observed at the small dose.This is demonstrated by the result of [η] of irradiated polymethylene terephthalates.

Key words: Polyesters, Radiation effect, Cross-linking and scission
