ABSTRACT:
Gem-diperoxyesters of the formula: ##STR1## where R is selected from methyl and ethyl; R.sub.1 is ethyl when R is ethyl; R.sub.1 is hydroxyalkyl of 1 to 7 carbon atoms when R is methyl; and each R.sub.2 is ##STR2## where each of R.sub.3, R.sub.4, and R.sub.5 is selected from hydrogen and alkyl, provided not more than one of R.sub.3, R.sub.4, and R.sub.5 is hydrogen, R.sub.3, R.sub.4, and R.sub.5 collectively containing from 2 to 12 carbon atoms.
The compounds are particularly efficient at varying temperatures from ambient to 60.degree. C. for the initiation of the polymerization of vinyl chloride. They also have high efficiency in the curing of polyester resins and in the polymerization of other monomers and comonomers having ethylenic unsaturation.
