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.
Claims31
A copolymer of at least one vinyl monomer and at least one high reactivity polyolefin having a terminal vinylidene content of at least about 40% and a number average molecular weight of about 200 to about 10,000, wherein said vinyl monomer is a compound of the formula CH2═C(R)X where R is hydrogen or C1-C6 alkyl and X is halogen, phenyl or phenyl substituted with C1-C4 alkyl, —COOR1 where R1 is hydrogen or C1-C12 alkyl, —C≡N, —C(O)NR2R3 where R2 and R3 are hydrogen or C1-C4 alkyl and may be the same or different, —(CH2)nCOOR1 where R1 is hydrogen or C1-C12 alkyl and n is an integer of from 1 to 4, or —CH═CHZ where Z is hydrogen or C1-C8 alkyl, or where both R and X are halogen.
