摘要

根据红外分析、顺磁共振、光电子能谱及化学分析结果，我们提出了氟塑料-46的辐射交联反应机理。交联点不一定如Bowers等由理论分析推断的在氟塑料-46的—CF,3,侧链上。我们认为可以由链侧自由基如,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42648618&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42648620&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42648619&type=,，直接复合成交联键，H型交联；或由链侧自由基和链端自由基复合通过支化而交联，即T型或Y型交联。后者机率更多些。

Abstract

On the basis of the results of IR analysis, ESR, ESCA and chemical analysis, we suggest the mechanism of radiation crosslinking of fluoropolymer Fs-46. The crosslinking point of Fs-46 is not on the side chain -CF,3,-group, as Bowers suggest with their theoratical analysis; we find that they may carried out with recombination of two side chain radicals directly, as,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42648621&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42648661&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42648622&type=, crosslinking with H type, or recombination of side chain radicals and chain end radicals through branching and then crosslinking. It is crosslinking with T type or Y type. The later one is the probable mechanism.
