摘要: 高分子染料的合成研究起于60年代初[1].1973年,Marechal等实现了无色高分子材料 与有色染料分子的化学键合[2~3].目前,高分子染料已广泛应用于化妆品、涂料、填料、食品等领域并开始探索在液晶显示、半导体材料、激光记录、非线性光学材料、亲和色谱等多种高科技领域中的应用[4].本文通过染料封端的聚醚聚氨酯预聚体与甲基丙烯酸甲酯(MMA)的共聚,合成了1种聚甲基丙烯酸甲酯(PMMA)型高分子染料,借助紫外光谱等分析手段对共聚过程 和共聚物进行了定性和定量分析,对该体系的自由基反应动力学进行了初步研究.

Abstract: A polymer dye has been synthesized by copolymerization of a dye-functionalized prepolymer based on polyurethane with methylmethacrylate. The composition of the copolymer has been analyzed by UV spectrometry. The effects of stock composition, reaction time and amount of initiator on the composition of copolymers have been studied. Results show that the dye-functionalized monomer is more reactive than methylmethacrylate in the course of copolymerization.
