  • High melt flow rate thermoplastic polyolefins produced in-reactor
    Patent number: 7226977
    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.
