Patent ID: 7652092

Claim:
A composition comprising a plasticized polyolefin composition comprising one or more polyolefins, one or more non-functionalized plasticizers, and a nucleating agent; wherein at least one of the non-functionalized plasticizers has a specific gravity of 0.86 or less and a viscosity index of 120 or more, and a kinematic viscosity of from 10 cSt to 1000 cSt at 100° C., wherein the polyolefin consists essentially of a propylene homopolymer, a propylene copolymer, an in situ propylene impact copolymer, or mixtures thereof and is present at 50 to 99.99 weight percent, based upon the weight of the composition, wherein the 1% secant flexural modulus of the polyolefin is 5 MPa or more and the 1% secant flexural modulus of the plasticized composition is 5 MPa or more, wherein ethylene homopolymers and copolymers having a weight average molecular weight of from 500 to 10,000 are substantially absent from the composition.
