通过4-乙烯基苯基氯化镁与合适的羰基化合物发生格氏反应，合成了一系列基于羟基烷基苯酮的新型可聚合光引发剂。将PI与不同的乙烯基单体进行自由基均聚和共聚，可得到与亲水或疏水树脂体系相容的聚合物PI。PI单体和聚合物具有优异的光引发活性，可与已知的最有效的PI相媲美，并表现出高的迁移稳定性。
A series of new polymerizable photoinitiators (PIs) based on hydroxyalkylphenones has been synthesized by Grignard reaction of 4-vinylphenylmagnesiumchloride with suitable carbonyl compounds. Radical homopolymerization and copolymerization of the PIs with various vinyl monomers yielded polymer PIs compatible with either hydrophilic or hydrophobic resin systems. The PI monomers and polymers are characterized by excellent photoinitiating activity comparable with the most efficient known PIs and exhibit high migration stability.
