Abstract

Abstract: Three polymerizable amines,EGDPM,DMPDA,EGMPM,were used as coinitiators for benzophenon photoinitaitor system.Their primary photochemistry process and photoinitiation kinetics in 1,6-Hexanediol Diacrylate system were investigated with UV-Vis spectroscopy and Photo-DSC.The result indicated that polymerizable amines type and their concentration played an important role on kinetics of photopolymerization rate and monomer conversation due to their primary photochemistry process properties.And increasing light intensity and temperature could lead to the increase of photopolymerization rate and the final conversion.

Key words: polymerizable amine, benzophenone combination initiator system, primary photochemistry process, photopolymerization kinetics
