Photopolymerization of glycerin triglycidyl ether based systems

Abstract

Photopolymerization process of glycerin triglycidyl ether based systems was studied by an FT-IR spectrometer. An increase in the rate of polymerization for glycerin triglycidyl ether was evident when 3,4-epoxycyclohexylmethyl-3′,4′-epoxycyclohexanecarboxylate was added to it. Its copolymerization mechanism was confirmed by using DSC analysis. The effect of ethoxylated trimethyol propane triacrylate on the rate of polymerization for glycerin triglycidyl ether was also studied, and the formation of interpenetrating network tightly cross-link was proposed.

Keywords
