Oxetanes: Curing properties in photo-cationic polymerization

Abstract

Novel five oxetane monomers were evaluated in photo-cationic curing system. The heat of polymerization of monomers in the formulation with cycloaliphatic diepoxide monomer were measured using photo-DSC. In the formulation, the viscosity were reduced effectively keeping high surface cure rate. Monofunctional oxetanes enhanced the flexibility of cured film. Difunctional oxetanes exhibited improved solvent resistance.
