Abstract
Abstract A photopolymerization initiator having as an active component thereof a benzophenone group-containing polyperoxyester represented by the general formula: wherein R 1 and R I ' independently stand for a tertiary alkyl group of 4 to 8 carbon atoms or a tertiary aralkyl group of 9 to 12 carbon atoms and R 2 and R 2 ' independently stand for a hydrogen atom, a tertiary alkoxy group of 4 to 8 carbon atoms, or a tertiary aralkyloxy group of 9 to 12 carbon atoms and a method for the photopolymerization of a radically polymerizable unsaturated compound by the steps of adding the aforementioned photopolymerization initiator to the aforementioned compound and expos - ing the resultant mixture to light.
