SCRATCH RESISTANT POLYOLEFINS Russian patent published in 2010 - IPC C08L23/16 C08K13/06 

FIELD: chemistry.

SUBSTANCE: invention relates to polyolefin substrates, for example to objects moulded from polypropylene, polyethylene or thermoplastic olefin, which is scratch resistant. Scratch resistance is achieved by adding an additive to polyolefin: maleated alpha olefin, functionalised long-chain alcohol or long-chain amine, and a primary or secondary amide of a fatty acid. The functionalised maleated alpha olefin is, for instance an ester or a partial ester of a maleated C₁₈-C₂₆alpha olefin with a tall fatty alcohol. The fatty acid amide is oleyl palmitate or stearyl erucamide, for example.

EFFECT: polyolefin compositions have high weather resistance, scratch resistance, good processibility, high mechanical strength, retain lustre well and are not sticky.
