  • Thermoformable polymer blend composition comprising styrene polymer, olefin polymer and block copolymer
    Patent number: 4386187
    Abstract: A thermoformable polymer blend composition comprising at least 50% by weight of an olefin polymer such as polyethylene or polypropylene, from 10 to 48% by weight of a styrene polymer and from 2 to 40% by weight of a thermoplastic styrenic block copolymer rubber, preferably a styrene-butadiene-styrene block copolymer, which acts as a compatibilizer for the olefin and styrene polymers in the blend. This blend can be formed on conventional machinery to give products having the beneficial properties of both types of polymers.
    Type: Grant
    Filed: January 16, 1981
    Date of Patent: May 31, 1983
    Assignee: Sweetheart Plastics, Inc.

  • Process of manufacturing lacquered articles of cold rolled abs resin
    Patent number: 3965230
    Abstract: Ductile composite of a cold-rolled rubber reinforced resin sheet and a normally embrittling layer. The rubber reinforced resin in sheet form is cold rolled to reduce its thickness to between 95 and 40 percent of the original thickness. The cold rolled sheet may then be shaped by deep drawing. A protective or decorative layer which would normally impair the impact strength and toughness of unrolled resin is applied to the cold rolled sheet to yield a tough, impact resistant composite.
