Abstract:
1. A heterogeneous blend composition comprising: a. from 1% to 99% by weight of the blend of a first polymer component comprising a copolymer of 5% to 35% by weight of the first polymer component consisting of ethylene derived units and 65% to 95% by weight of the first polymer component of propylene derived units having a crystallinity of 0.1% to about 25% from isotactic polypropylene sequences, a melting point of from 45° C. to 105° C., and wherein the Melt Flow Rate (MFR@230° C.) of the first polymer component is between 300 g/10 min to 5000 g/10 min; and b. from 1% to 99% by weight of the blend of a propylene polymer component comprising random copolymers 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., wherein the first polymer component has less than 1000 ppm of reaction products arising from the chemical reaction of a molecular degradation agent; wherein the heterogeneous blend composition has a melting temperature greater than about 90° C.
