Abstract
The present invention relates to novel compositions useful in coating, adhesive, structural, film, sheet, pipe, toys, house siding, asphalt, thermoplastic, elastomer and other applications. The novel compositions comprise copolymers of at least one vinyl and/or vinylidene monomer and at least one high reactivity polyolefin. The copolymers are produced by polymerizing at least one high reactivity polyolefin and at least one vinyl monomer in the presence of a free radical initiator.

A graph copolymer formed by the free radical polymerization of reactant components consisting essentially of (1) CH2═C(R)COOR1 where R is hydrogen or C1-C4 alkyl and R1 is hydrogen or C1-C10 alkyl an (2) a high reactivity polyolefin of a C3-C20 olefin having a terminal alkylvinylidene content of at least about 80% and a number average molecular weight of about 200 to about 10,000.
