Scratch resistant polyolefins

摘要

Polyolefin substrates, for example polypropylene, polyethylene or thermoplastic olefin molded parts, are made scratch resistant by the incorporation therein of an additive combination of a maleated alpha-olefin functionalized with a long chain alcohol or long chain amine and a primary or secondary fatty acid amide. The present polyolefins exhibit good weatherability, scratch resistance, good processability, good mechanical strength, good gloss retention and are non-sticky. The functionalized maleated alpha-olefin is for example the ester or half ester of maleated C₁₈-C₂₆ alpha-olefin with tallow fatty alcohol. The fatty acid amide is for example oleyl palmitamide or stearyl erucamide.
