  • Stabilized polyester compositions
    Patent number: 4414348
    Abstract: There is disclosed a method for stabilization of polyester resins by incorporating in the resins novel polymeric diphenylamine compounds, produced by reacting diphenylamine with a dialkylalkenylbenzene or a dihydroxyalkylbenzene in the presence of an acid catalyst.
    Type: Grant
    Filed: January 26, 1983
    Date of Patent: November 8, 1983
    Assignee: The Goodyear Tire & Rubber Company
    Inventors: Richard E. Gloth, James J. Tazuma, Max H. Keck
  • Linear block copolyesters having improved slip characteristics
    Patent number: 4348510
    Abstract: This invention provides for novel linear thermoplastic block copolyesters derived from dicarboxylic acids or dialkyl esters thereof, alkylene glycols and dihydroxy terminated polydimethylsiloxane block copolymers. Films, tapes, sheeting and other extruded and molded articles prepared from said copolyesters exhibit improved clarity and when tested in accordance with ASTM test method D-1894 exhibit improved nonsticking properties.

  • Halogen containing copolyester resins
    Patent number: 4254243
    Abstract: The invention relates to copolyesters of ethylene terephthalate-tetrachlorobenzenedimethylene terephthalate. They can be random or block copolyester. The products have high second order transition temperatures and can be formed into products that can be sterilized.
    Type: Grant
    Filed: February 22, 1979
    Date of Patent: March 3, 1981
    Assignee: The Goodyear Tire & Rubber Company
    Inventor: Max H. Keck
  • Linear copolyesters containing tertiary butyl isophthalic acid
    Patent number: 4223126
    Abstract: Novel compositions of matter comprising polymethylene terephthalate t-butyl isophthalate copolyesters wherein the t-butyl isophthalate repeating units range from 1 to 50 mole percent and the ethylene terephthalate repeating units range from 99 to 50 mole percent, said percentages being based on the sum of the moles of ethylene terephthalate and t-butyl isophthalate repeating units in said compositions.
    Type: Grant
    Filed: August 2, 1979
    Date of Patent: September 16, 1980
    Assignee: The Goodyear Tire & Rubber Company
    Inventor: Max H. Keck
  • Method for accelerating the crystallization rate of crystallizable polyester resin
    Patent number: 4098845
    Abstract: This invention relates to crystallizable polyester compositions having improved molding characteristics. Crystallization rates and properties are improved by the addition of a polymer derived from meta or para diisopropenyl benzene and such polymers terminated by .alpha.-methyl styrene.
    Type: Grant
