ABSTRACT:
Photopolymerization initiators of the general formula: ##STR1## wherein R.sub.1 and R.sub.1 ' independently stand for a tertiary alkyl group or a tertiary aralkyl group and R.sub.2 and R.sub.2 ' independently stand for a hydrogen atom, a tertiary alkoxy group, or a tertiary aralkyloxy group are disclosed. They are useful for effecting polymerization of radically polymerizable unsaturated compounds. Tetra peroxy esters of benzophenone are preferred.
