Abstract:
1. A homogeneous 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 hexene derived units and 65% to 95% by weight of the first polymer component of 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.) 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; and b. from 1% to 99% by weight of the blend of a second polymer component comprising homopolypropylene and/or a random copolymers of propylene and alpha-olefin, 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 flex modulus (1% secant) of the homogeneous blend is less than 45 kpsi.
