ABSTRACT:
The thermal stability of alpha-substituted acrylate graft copolymers can be improved by (a) making a graft copolymer comprising a backbone of a propylene polymer material having graft polymerized thereto monomers comprising (i) a 1-3 C alkyl-substituted acrylic acid and (ii) an ester of a 1-3 C alkyl-substituted acrylic acid, wherein the total amount of polymerized monomers is about 20 to about 240 parts per hundred parts of the propylene polymer material and the amount of (i) is about 1 to about 20%, based on the total weight of monomers, and (b) removing any unreacted grafting monomer from the resulting grafted propylene polymer material, decomposing any unreacted initiator, and deactivating any residual free radicals in the material.
