Claims7
A thermoplastic polymer composition consisting of:
- (a) a thermoplastic polymer, wherein the thermoplastic polymer is a polyethylene;
- and
- (b) a nucleating agent, the nucleating agent comprising a compound conforming to the structure of Formula (I)
- wherein x is a positive integer;
- R1, R2, R3, R4, R5, and R6 are hydrogen;
- each M1 is a metal cation selected from the group consisting of zinc cations;
- y is the valence of the metal cation;
- z is a positive integer;
- wherein the values of x, y, and z satisfy the equation x=yz;
- and
- (c) optionally, one or more additional components selected from the group consisting of additional thermoplastic polymers, antioxidants, anti-blocking agents, fillers, reinforcing agents, nucleating agents, clarifying agents, acid scavengers, polymer processing additives, polymer cross-linking agents, slip agents, and fatty acid ester compounds.
