Abstract
Novel tertiary alkyl peresters of tertiary hydroperoxides are used as polymerization initiators wherein the peresters are characterized by the tertiary alkyl group of the acid moiety having at least two alkyl groups of two or more carbon atoms and the tertiary alkyl group of the hydroperoxide has at least five carbon atoms. Typical is the polymerization of certain vinyl monomers such as vinyl chloride.
