摘要

同一分子中既含有给电子生色基团和缺电子双链的一类功能性单体

由于在荧光光谱和光化学行为等方面表现出很多有趣的现象

因而备受注目［１

２］．而对含不同给电子杂原子如Ｎ、Ｓ、Ｏ等的功能性单体

因其给电子能力不同

它们所表现出的性质特别是光化学性质也有一定差别．对于含供电子Ｎ原子的丙烯酰类单体如８丙烯酰氧喹啉（ＡＱ）

Ｎ甲基丙烯酰Ｎ’嘧啶哌嗪（ＭＰＭＰ）等的合成、聚合、光物理及光化学行为

Abstract

The photopolymerization of acrylonitrile(AN) sensitized by N-acrylyl phenothiazine(APT) and its oxides

i.e. N acrylyl phenothiazine sulfoxide(APTO) and N acrylyl phenothiazine sulfdioxide(APTDO) was studied kinetically. It was found that the photopolymerization rate equations and E a were obtained as following: Rp ∝ 0.44 0.84

Ea =23.23kJ/mol; R p ∝ 0.44 0.87

E a =22.97kJ/mol; R p ∝ 0.47 0.88

E a= 22.33kJ/mol.From the UV analysis for P(AN) sensitized byAPTO

it was confirmed that APTO not only sensitized the photopolymerization of AN but also entered into the P(AN) chains.
