  • Patent number: 3981958
    Abstract: A new graft copolymer composed of an ethylene/propylene/non-conjugated diene terpolymer backbone and a homopolymerized or copolymerized methacrylic ester graft moiety. The graft copolymer is produced by grafting a lower alkyl methacrylate alone or in mixture with other ethylenically unsaturated monomer or monomers copolymerizable therewith to an ethylene/propylene/non-conjugated diene terpolymer in the presence of a radical polymerization initiator. The graft copolymer is useful as resinous or rubbery component in a coating or binding composition for treating various inorganic and organic materials including glass and fibers.
