1.丙烯腈,丙烯腈—氯代醋酸乙烯,丙烯腈—丙烯骏甲酯,丙烯腈—丙烯酸乙酷,丙烯腈—丙烯酸,丙烯腈—丙烯酰胺和丙烯腈—乙烯吡啶在濃无机盐溶液中的光聚合反应可以用效率好的有机光敏剂引发聚合,在5小时左右除与氯代醋酸乙烯共聚的转化率较低外其余的都可达到或超过90%。 2.光敏剂对光聚合反应有较大的影响,我们找到了性能优良的有机光敏剂。 3.用此法进行光聚合反应所得之母液,不分层,为透明的液体,壁上稍有小汽泡,这些母液可以用来直接抽丝,抽出的丝性质优良,共聚物还容易染色。
1. Acrylonitrile, acrylonitrile-vinyl chloroacetate, acrylonitrile-acrylonitrile, acrylonitrile-acrylic acid, acrylonitrile-acrylic acid, acrylonitrile-acrylamide and acrylonitrile-vinylpyridine in concentrated inorganic salt solution Photopolymerization can initiate polymerization with a highly efficient organic photosensitizer and reach or exceed 90% in about 5 hours except for the lower conversion with vinyl chloroacetate. 2. Photosensitizer on the photopolymerization reaction has a greater impact, we found a good performance of the organic photosensitizer. 3. The mother liquor obtained by the photopolymerization reaction by this method is a transparent liquid with a slight bubble on the wall. These mother liquors can be used for direct spinning, and the extracted filaments are excellent in quality and the copolymer is easily dyed .
