Polypropylene blends according to the current invention provide lower bonding temperatures and wider bonding windows without the increased smoke generation associated with high solubles homopolymers.

Abstract: A thermoplastic polyolefin having a melt flow rate of 20 dg/min or higher at 230° C. is produced in reactor without visbreaking. By controlling ratio of the weight average molecular weight of the xylene soluble fraction to the weight average molecular weight of the xylene insoluble fraction, a high melt flow thermoplastic polyolefin can be produced having a good balance of impact and stiffness, tensile elongation at break and gloss properties. Optionally, the ratio of the melt flow rate of the homopolymer phase to the melt flow rate of the total thermoplastic polyolefin can also be controlled. By compounding thermoplastic polyolefins according to the current invention with one or more modifiers, additional compositions can be produced having improved resistance to solvents.

One embodiment of the invention comprises creating a melt-blend of blending composition, up to 50% by weight thermoplastic scrap and up to 15% by weight poly(ethyl-co-vinyl) acetate wherein the blending composition comprises an impact polypropylene, impact modifier and plasticizer. The polypropylene, impact modifier and plasticizer are selected to meet requirements of flexible thermoplastic compositions useful in vehicle interiors. In another embodiment of the invention a random polypropylene is used.

Abstract: Polypropylene resin compositions are provided that are useful in the production of thermoformed articles and biaxially oriented polypropylene films (BOPPs), tapes and fibers. The resins of the present invention are blends of high crystalline (low solubles) polypropylene homopolymer and an ethylene/propylene random copolymer (RCP).

In addition, the use of high crystalline polypropylene homopolymers in the blends imparts improved stiffness to the finished films while maintaining good processability of the blends. Such polypropylene compositions are effectively produced by in-reactor blending of a high crystalline propylene homopolymer and a propylene/ethylene random copolymer.
