摘要: 以4-羟基二苯甲酮(HBP)、甲苯-2,4-二异氰酸酯(TDI)、4,4′-二羟基二苯甲酮(DHBP)为原料,通过两步反应,合成了一种大分子量二苯甲酮光引发剂:HBP-TDI-DHBP-TDI-HBP(HTDTH).通过实时红外研究了HTDTH的光聚合动力学.结果表明,HTDTH是一种有效的光引发剂.采用HTDTH/胺光引发体系引发二缩三丙二醇二丙烯酸酯(TPGDA)聚合时,随着胺和引发剂浓度的增大,反应速率(Rp)和单体最终转化率(P)同时增大.

Abstract: A benzophenone derivative photoinitiator with high molecular weight,HBP-TDI-DHBP-TDI-HBP(HTDTH),based on 4-hydroxy benzophenone(HBP),toluene-2,4-diisocyanate(TDI) and 4,4’-dihydroxy benzophenone(DHBP),was synthesized and characterized by FTIR.The photopolymerization kinetics showed that HTDTH was an effective photoinitiator.When HTDTH and amine were used to initiate polymerization of acrylates,both rate of polymerization(Rp) and final conversion(P) increased with increase of amine and HTDTH concentration.

Key words: photopolymerization, benzophenone derivative/amine, kinetics
