Claims20
A thermoplastic polymer composition, comprising
- thermoplastic polymer,
- an organic peroxide, and
- a nucleating composition comprising:
- (a) a first nucleating agent, which comprises a cyclic dicarboxylate salt compound;
- and
- (b) a second nucleating agent, which comprises talc,
- wherein the cyclic dicarboxylate salt compound has the formula (I):
- wherein said thermoplastic polymer is a heterophasic propylene copolymer comprising a matrix phase comprising propylene and a dispersed phase comprising an ethylene-alpha-olefin elastomer, wherein the heterophasic propylene copolymer has a melt flow index of at least 1 dg/min.
