Abstract

Abstract: Kinetics of dental composite initiated by camphorquinone(CQ)/ethylene glycol 3-morpholine-propionate methacrylate(EGMPM) was monitored by Photo-DSC.The results showed that the increase of the concentration of initiator system and the light intensity led to the increase of the final double bond conversion and the polymerization rate.The results proved the relationship of Rp∝(I₀[CQ][EGMPM])^1/2.

Key words: photopolymerization, amine coinitiator, kinetics, Photo-DSC
