摘要

利用裂解色谱研究了聚砜辐射交联前后结构的变化。从裂解谱图中，各裂解产物的相对含量随辐照剂量的变化规律，推测了辐射交联发生的位置及可能的交联机理。利用谱图中甲苯与苯的相对含量比与辐照剂量的关系，求得了不同温度下聚砜的凝胶化剂量，所得值与溶解度法求得值比较一致。

Abstract

Radiation induced crosslinked polysulfone was studied by means of Pyrolysis Gas Chromatography (PGC). We suggested the possible crosslinking sites of polysulfone according to the change of the relative content of pyrolytic products with the radiation dose. The gelation doses of the polysulfone crosslinked at different temperature were obtained from the relationship of peak height ratio of benzene: toluene in pyrolytic spectra to radiation dose which were quite consistent with the value obtained from other method.
