科学技术的进步,对新材料的要求逐步向着多功能和高性能的方向发展,单组分材料已难于满足这种要求,在高分子材料方面,人们采用了共混、接枝、嵌段等方法以达到改善和提高性能的目的。感光性高分子是一类很重要的功能材料,至今,大部分采用自由基聚合方式制备。近年来,阳离子引发体系发展很快,特别鎓盐光引发体系受到很大的重视,发展迅速。目前自由基聚合及阳离子聚合已经成为合成感光性高分子材料的二种最 The progress of science and technology, the requirements of new materials and gradually toward the multi-functional and high performance direction, one-component materials have been difficult to meet this requirement, in the polymer materials, people have adopted blending, grafting, block Method to achieve the purpose of improving and improving performance. Photosensitive polymers are a kind of very important functional materials, so far, most of them are prepared by free radical polymerization. In recent years, the cationic initiator system developed rapidly, especially onium salt photoinitiation system has received great attention, rapid development. At present, free radical polymerization and cationic polymerization have become the most two kinds of synthetic photosensitive polymer materials
