| titleOfInvention | Soft heterogeneous isotactic polypropylene compositions |
| abstract | The present invention also discloses 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 predominantly of alpha olefin 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 b) from 1% to 99% by weight of the blend of a second polymer component comprising isotactic polypropylene and random copolymers of isotactic propylene, wherein the percentage of the copolymerized alpha-olefin in the copolymer is between 0.0% 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. |
