Liquid photopolymers curable to fire-retardant, hydrolysis resistant compositions

摘要

Novel fire-retardant and hydrolysis resistant, liquid, photosensitive compositions are disclosed comprising (1) the reaction product of (a) an aliphatic unsaturation containing chlorendate, and (b) a non-ester containing polythiol, said (a) and (b) being reacted non-stoichiometrically; (2) a member of the group consisting of either (a) or (b) in an amount up to that sufficient to react with the excess of the other in (1) and a liquid acrylate monomer or oligomer, and (3) at least one photoinitiator. Acrylates or methacrylate monomers are optionally added to the composition.
