  • Clear impact-resistant syndiotactic polypropylene
    Publication number: 20040034167
    Abstract: Syndiotactic polypropylene blends having a unique set of mechanical properties may be prepared by blending syndiotactic polypropylene with an ultra low density polyethylene and, optionally, an isotactic polypropylene random copolymer. The syndiotactic polypropylene blends of the present invention have been found to have improved impact strength, reduced haze, increased light transmittance, and reduced flexural modulus. It has been determined that the addition of about 10 to about 50 wt % of an ultra low density polyethylene plastomer to a syndiotactic polypropylene can greatly enhance mechanical toughness, particularly at low temperatures, while maintaining good optical clarity. These results are made possible by using a sPP material with good optical clarity and dispersing the ULDPE plastomer uniformly throughout the sPP matrix to act as a sort of impact modifier.

  • Polymer blends of olefin elastomers, syndiotactic polypropylene and styrene-butadiene-styrene copolymers, method of blending, products made therefrom, and method of making products
    Patent number: 6242532
    Abstract: A blend composition including from about 1 to about 99 weight percent syndiotactic polypropylene (sPP) and from about 99 to about 1 weight percent styrene-butadiene-styrene block copolymer (SBS) and olefin elastomer, based on the weight of the sPP, SBS and olefin elastomer. A method of making the composition includes contacting the sPP, SBS and olefin elastomer at a temperature above the melting point of the sPP and olefin elastomer, with useful articles formed therefrom.
