ABSTRACT:
Acrylate graft copolymers prepared in a two-stage process by first reacting a backbone polymer, such as 1,2-polybutadiene, an alkylidene norbornene polymer or an ethylene/propylene/alkylidene norbornene terpolymer, with, for example, a mixture of dinitrogen tetroxide and oxygen to form a nitrooxidized polymer having incorporated therein nitro and peroxy nitrate functions which serve, in the second stage of the process, as sites for the subsequent graft polymerization of an acrylate monomer are disclosed. The thus-formed graft copolymers comprise from about 5 to about 80 weight percent of the backbone polymer with the balance being furnished by the acrylate monomer.
