Patent ID: 7390574

Claim:
A polyolefin composition comprising a polyolefin substrate and an amount effective to improve the scratch resistance of said polyolefin substrate of an additive combination of a functionalized maleated alpha-olefin and a primary or secondary fatty acid amide, where the functionalized maleated alpha-olefin is an ester or half ester of the formula where R is C 16 to C 24 alkyl, R 1 and R 2 are indedendently hydrogen, C 1 -C 22 alkyl or C 2 -C 22 , alkenyl where at least one of R 1 and R 2 are C 12 -C 22 alkyl or alkenyl and n is an integer such that the average molecular weight is between about 20,000 and about 50,000.
