Patent ID: 7943702

Claim:
A molded article comprising a thermoplastic composition, wherein: (i) the thermoplastic composition has been molded in a tool which has been polished to a SPE 1 finish and heated to between 100° F. and 170° F. so that the resulting molded article (A) has a high gloss of above 90% as measured by a gloss meter, (B) has a scratch resistant surface, and (C) is ductile at 0° C. or -30° C. as measured by a multiaxial impact tester; and, (ii) the thermoplastic composition comprises in admixture: (a) a crystalline polybutene-1 in an amount between 0.1% and 60% by weight of the composition; (b) a crystalline polypropylene in an amount between 60% and 80% by weight of the composition; (c) a thermoplastic polyolefin elastomer in an amount between 15% and 40% by weight of the composition, the thermoplastic polyolefin elastomer comprising ethylene and propylene monomer units; (d) a nucleating agent comprising a solid bicyclic dicarboxylic acid salt; and (e) optionally a coupling agent which couples (a), (b), (c) and (d) together in an amount up to 10% by weight.
