MASSES A BASE D'ESTERS ACRYLIQUES, POLYMERISABLES AU MOYEN DE RAYONS ULTRA-VIOLETS

摘要

An improved process for the photopolymerization of compositions including photopolymerizable acrylic or methacrylic acid esters and an initiator (e.g., a benzoin compound) is disclosed. The addition of 0.1 to 20 weight percent (based on the amount of polymerizable material) of an organic phosphite substantially reduces the polymerization time of the resulting composition.
