Abstract

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(R_p) and final conversion(P) increased with increase of amine and HTDTH concentration.

Key words: photopolymerization, benzophenone derivative/amine, kinetics
