自Ter Meer于1986年首次发现光致变色现象以来,人们已发现和合成了多种光致变色化合物和由它们组成的光致变色材料。其中,由光致变色聚合物制成的光致变色材料,由于价格较低、颜色均匀、不易为溶剂抽提和与其它高聚物相容性好等特点,在国内外都受到广泛的重视。为了开发具有实际应用价值的光致变色材料,我们在聚醚型、聚硅氧烷型光致变色聚合物的研究基础上,选择工业生产的丙烯酸酯和甲基丙烯酸酯类以不同摩尔比和组合进行共聚,再将共聚物汞化并与二苯基硫代卡巴腙反应,制得了四种与其它高聚物相容性好的光致变色三元共聚丙烯酸酯。合成途径如下:
Since Ter Meer first discovered photochromism in 1986, a variety of photochromic compounds and photochromic materials have been discovered and synthesized. Among them, the photochromic polymer made of photochromic materials, due to lower prices, uniform color, not easy for solvent extraction and compatibility with other polymers, etc., are widely valued at home and abroad . In order to develop a photochromic material with practical value, based on the research of polyether and polysiloxane type photochromic polymers, we choose commercially-produced acrylates and methacrylates with different molar ratios and In the copolymerization, the copolymer was then amalgamated and reacted with diphenylthiobarbazone to prepare four photochromic terpolyacrylates with good compatibility with other polymers. The synthetic route is as follows:
