  • Polyester/polycarbonate blends having improved clarity and impact strength
    Patent number: 5194523
    Abstract: Disclosed are clear thermoplastic molding compositions comprising an aromatic polycarbonate, a polyester of terephthalic acid and 1,4-cyclohexanedimethanol, and the copolymeric transesterification product of the polycarbonate and polyester.
    Type: Grant
    Filed: May 30, 1991
    Date of Patent: March 16, 1993
    Assignee: Eastman Kodak Company

  • Blends of polyester-ethers with ethylene-acrylic acid copolymers
    Patent number: 4950717
    Abstract: A compatible polymer blend, comprising(i) about 10 to 90 weight percent of an ethylene-acrylic acid copolymer comprising from about 10 to 50 mole percent acrylic acid monomer units; and(ii) about 90 to 10 weight percent of a polyester-ether derived from 1,4-cyclohexane dicarboxylic acid, 1,4-cyclohexane dimethanol and poly(oxytetramethylene) glycol.
    Type: Grant
    Filed: June 2, 1989
    Date of Patent: August 21, 1990
    Assignee: Eastman Kodak Company
    Inventors: Robert W. Seymour, Thomas E. Flora
  • Blends of poly(etheresters) and polyesters
    Patent number: 4904748
    Abstract: Disclosed are compositions comprising a blend of blends comprising(A) about 98-2 weight % of a flexible poly(etherester) having recurring units from 1,4-cyclohexanedicarboxylic acid having a trans isomer content of at least 70%, a glycol component consisting essentially of 1,4-cyclohexanedimethanol and poly(oxytetramethylene) glycol.(B) about 2-98 weight % of a relatively rigid polyester,the blends having improved stiffness and notched Izod impact strength when compared to the poly(etherester) alone.
    Type: Grant
    Filed: February 3, 1988
    Date of Patent: February 27, 1990
    Assignee: Eastman Kodak Company
    Inventors: Robert W. Seymour, Thomas E. Flora
  • Compatible blends of polyester-ethers and polycarbonates
    Patent number: 4897453
    Abstract: Disclosed is a thermoplastic blend of a (1) polycarbonate and (2) a polyester-ether derived from 1,4-cyclohexanedicarboxylic acid, 1,4-cyclohexanedimethanol, poly(oxytetramethylene) glycol and, optionally, a polyfunctional compound. The blends possess a unique combination of properties, some of which are characteristic of compatible blends and others which are characteristic of incompatible blends.
