Patents by Inventor Terence C. Middlebrook

Terence C. Middlebrook has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 4489187
    Abstract: The loss in tensile of a polypropylene blend with a conjugated diene/monovinylarene rubbery block copolymer can be prevented by including in the blend an effective amount of a polychloroprene, followed by curing the composition with a curative which cures substantially only the polychloroprene component.
    Type: Grant
    Filed: February 29, 1984
    Date of Patent: December 18, 1984
    Assignee: Phillips Petroleum Company
    Inventor: Terence C. Middlebrook
  • Patent number: 4456727
    Abstract: In a process of curing solution-polymerized synthetic rubbers, the improvement effected is the retardation of the cure rate and increasing of time to scorch by the addition of small amounts of a heat-curable phenol-formaldehyde resin. This method of controlling cure rate and scorch time complements other techniques known in the art (e.g., cure accelerators), and can be used to adjust the properties of solution-polymerized rubbers to match those of emulsion-polymerized rubbers.
    Type: Grant
    Filed: April 30, 1982

    Inventor: Terence C. Middlebrook
  • Patent number: 4424259
    Abstract: Shaped articles are formed from a composition comprising a mixture of (1) a thermoplastic elastomer copolymer of at least one conjugated diene and at least one vinyl arene, preferably a butadiene-styrene block copolymer and (2) at least one poly(vinyl arene) resin, preferably poly(alphamethyl styrene), which is thermally bonded sans adhesive to smooth plastics consisting essentially of polymers or copolymers of vinyl chloride.

  • Patent number: 4236715
    Abstract: An amusement device in which a shaped object prepared from a blended mixture of highly oil-extended butadiene-styrene radial teleblock copolymers adheres on impact to the flat surface of a target material.
    Type: Grant
    Filed: September 19, 1978
    Date of Patent: December 2, 1980
    Assignee: Phillips Petroleum Company
    Inventor: Terence C. Middlebrook
  • Patent number: 4126662
    Abstract: An injection molded polymer having limited surface gloss is provided by preparing an admixture of an injection moldable polymer substrate and an additive chosen from among the group consisting of finely divided textile fibers, finely divided hydrocarbon polymers, and blowing agents and injection molding an article from the admixture. In the embodiment of the invention employing blowing agents the admixing is carried out at a temperature below that at which the blowing agent is activated and the injection molding is carried out at a temperature sufficient to activate the decomposition of the blowing agent.
