  • Thermoplastic elastomer compositions for low pressure molding
    Patent number: 4400483
    Abstract: Compositions comprising a thermoplastic elastomer, e.g., radial block butadiene/styrene copolymer, solid resinous polymer, e.g., vinyl-substituted aromatics, and one or more specific polar compounds. The specific polar compounds are chosen from among simple and polymeric alkaline glycols, their mono and dialkyl ethers; ethanolamines, isopropanolamines, and their hydrocarbylsubstituted derivatives; liquid acrylonitrile/butadiene polymers; acrylonitrile/butadiene blends with homopolymers of polyvinyl chloride and styrene/acrylonitrile copolymers; and mixtures thereof. A method using these compositions for producing molded objects at a molding pressure of up to about 200 psig. Molded objects produced from these compositions and molded objects produced by this method of molding.
    Type: Grant
    Filed: March 27, 1981
    Date of Patent: August 23, 1983
    Assignee: Phillips Petroleum Company
    Inventors: Roy W. Siedenstrang, William H. Cornell
