브롬화 에폭시 아크릴레이트 합성 및 열변색 특성

Abstract

Polymers with excellent refractive index have been widely used for optical lens and parts in electronic electricity because of its light weight. Among them, a brominated epoxy acrylate shows high refractive index but is discolored during curing process by heating. Since the discoloration has been affected by polymerization inhibitor and reactive monomer. mixtures with different contents of polymerization inhibitor, hydroquinone mono methyl ether and reactive monomer, styrene were cured by heating and their properties, such as refractive index, viscosity, and color, were investigated as a function of composition of both components. Also, thermal discoloration of the cured mixture were analysed as a function of triphenylphosphite content as a thermal stabilizer.
