哌嗪-苯胺二环氧系感光性高分子的研究 Ⅰ.合成及其感光性

用哌嗪和N,N-二环氧丙基苯胺(苯胺二环氧)通过线型加成聚合反应,得到一种新型高分子。这种高分子与有机多卤化物所组成的感光体系,在近紫外光(300—400nm)的照射下,发色的同时交联固化。最低固化光量为78mJ·cm^-2。发色吸收峰初始为660nm,随曝光量增大,吸收增大,峰值向650nm俯移。所得蓝绿色图像可用稀酸显影。硫杂蒽酮类化合物是这些体系很有效的增感剂。

PHOTOPOLYMERS DERIVED FROM PIPERAZINE AND DIEPOXYCOMPOUNDS OF ANILINE (I). SYNTHESIS AND PHOTOSENSITIVITY

A new polymer was obtained by linear addition polymerization of N,N-diepoxypropyla-niline with piperazine. Some photosensitive systems can be formed from the polymer with polyhalides and can be photocolorized and photocured simultaneously upon irradiating with near UV(300-400 nm). The minimum quantity of exposure energy required for photocuring these systems is 78mJ·cm-8. The absorption peak of the chromophore increases with increasing exposure time and moves from 660 nm to 650 nm. The blue-green image obtained upon irradiating can be developed by dilute acid-water solution. The thioxanthone compounds are used as very effective sensitizers for the systems.
