Kathleen Perevosnik 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).

  • Blends of olefinic thermoplastic vulcanizate with high impact polystyrene
    Patent number: 6846877
    Abstract: An olefinic thermoplastic vulcanizate is blended with a rubber-modified monovinylidene aromatic monomer, utilizing a flexible block copolymer as compatabilizing agent. The resulting composition demonstrates improved miscibility and bonding characteristics and increased hardness not previously achievable using unmodified thermoplastic vulcanizates.
    Type: Grant
    Filed: December 26, 2002
    Date of Patent: January 25, 2005
    Assignee: Advanced Elastomer Systems, L.P.
    Inventors: Sunny Jacob, Kathleen Perevosnik, Joseph E. Pfeiffer
  • Thermoplastic elastomers having improved adhesive proterties
    Patent number: 6790911
    Abstract: A thermoplastic vulcanizate prepared by dynamically vulcanizing a halogenated butyl rubber within a mixture that includes the halogenated butyl rubber and from about 10 to about 100 parts by weight of a crystalline thermoplastic resin per 100 parts by weight rubber, to thereby form a thermoplastic vulcanizate, where the thermoplastic resin includes a resin other than polyethylene, melt mixing the thermoplastic vulcanizate with about 5 to about 75 parts by weight of polyethylene resin per 100 parts by weight rubber, from about 3 to about 60 parts by weight of a tackifier per 100 parts by weight rubber, and from about 5 to about 250 parts by weight of a block copolymer containing at least the structure S-B/S-S per 100 parts by weight rubber, where the S block of the block copolymer has a glass transition temperature above about 25° C., the B/S block has a glass transition temperature below about 25° C.
