Novel photosensitizers are disclosed which are particularly useful in photopolymerizable organopolysiloxane and silicone resins. The photosensitizers are themselves organopolysiloxanes which contain at least one silicon-bonded benzophenone-containing radical. Synthesis methods are disclosed for preparing these photosensitizers which employ, as starting materials, an alkenyloxy-substituted benzophenone and a silicon compound containing at least one silicon-bonded hydrogen atom.
本发明公开了新型光敏剂,这些光敏剂在可光聚合的有机聚硅氧烷和硅树脂中特别有用。 这些光敏剂本身是有机聚硅氧烷,含有至少一个硅键合的二苯甲酮基。 本发明公开了制备这些光敏剂的合成方法,这些方法采用烯氧基取代的二苯甲酮和含有至少一个硅键合氢原子的硅化合物作为起始原料。
