Abstract
The present invention relates to a novel antioxidant-peroxide compound of Structure A, EQU (Y--[--R--OO--X).sub.x --An].sub.y A in which the definitions of X, Y, R, An, x, and y are given in the Summary of the Invention section, for example, t-butyl peroxy-3-(3,5-di-t-butyl-4-hydroxyphenyl)propionate, processes for producing polymeric compositions of enhanced oxidative stability via initiation of polymerization of ethylenically unsaturated monomers, curing of elastomers and unsaturated polyester resins, modification of polypropylene and other polymers and copolymers, and crosslinking of olefin polymers and copolymers, and the resulting polymers having enhanced oxidative stability.
