Abstract

The synthesis of acrylates with an isocyanurate substituent that show significant volume expansion on radical photo-polymerization is reported. The acrylate consisting of benzyl bisurethane moieties exhibits the largest volume expansion among them and contributes to restrict volume change upon its radical photo-copolymerization with a diacrylate exhibiting volume shrinkage. Furthermore, a correlation is revealed between the volume change behavior and the polymer structure through the radical photo-polymerization of the isocyanurate core-based diacrylate with benzyl bisurethane moieties under various concentration conditions.

Keywords: acrylate; isocyanurate core; radical photo-polymerization; volume expansion.
