Patent ID: 8263707

Claim:
A heterogeneous blend composition comprising; a. from 1% to 20% by weight of the blend of a first polymer component comprising a copolymer of 5% to 14% by weight of the first polymer component ethylene derived units and 65% to 95% by weight of the first polymer component propylene derived units, wherein said first polymer component has: i) a crystallinity of 0.1% to about 25% from isotactic polypropylene sequences, ii) a melting point of from 45° C. to 105° C., iii) a Melt Flow Rate (MFR@230° C.) of between 300 g/10 min to 5000 g/10 min, and iv) less than 1000 ppm of reaction products arising from the chemical reaction of a molecular degradation agent; b. from 80% to 99% by weight of the blend of a second polymer component comprising homopolypropylene and/or a random copolymer of propylene, wherein the percentage of the copolymerized alpha-olefin in the copolymer is between 0 and 9% by weight of the second polymer component and wherein the second polymer component has a melting point greater than about 110° C.; and c. from 1% to 20% by weight of the blend of a plasticizer; where the first polymer component is dispersed within the second polymer component, the dispersed particles of the first polymer component having a diameter less than 10 μm; and where the blend has: a Melt Flow Rate (ASTM D 1238) greater than 50 g/10 min, an elongation (break) greater than 300%, a flexural Modulus (1% secant) in kpsi of less than 30, a tensile strength in psi greater than 1200, and a die C tear in lbf/in greater than 250.
