摘要

用IR、UV、NMR和GC/MS等手段检测并分析了经γ辐照后E 51-618环氧树脂的环氧值，羟基、羧基和不饱和键的含量、聚合度以及生成气态产物的变化，发现了该体系未曾报道过的辐射引发产物，如二聚体（化合物Ⅰ,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650788&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650792&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650787&type=,）、被氧化的羟基化合物（化合物Ⅳ,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650804&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650796&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650805&type=,）和气态产物（化合物Ⅴ,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650798&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650810&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650799&type=,）,论述了该体系的自由基反应机制。

Abstract

The coloration, viscosity increasing and gaseous products induced by γ-ray in epoxy compounds have been reported previously. The changes of epoxide equivalent, hydroxy, carbonyl, unsaturated bond, degree of polymerization and gaseous products in E 51-618 epoxy resin γ-irradiated have been examined and evaluated by means of IR, UV, NMR and GC/MS, etc. The radiation induced products such as dipolymer(compound Ⅰ,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650800&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650819&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650818&type=,), oxidized hydroxy compound (compound Ⅳ,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650811&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650822&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650821&type=,) and gaseous products (compound Ⅴ,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650813&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650815&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650824&type=,) have been first found. The radical reaction machenism in above system was discussed.
