  • Hydrolysis resistant polyester films
    Patent number: 9333692
    Abstract: A biaxially oriented polyester film comprising polyester and at least one hydrolysis stabilizer selected from a glycidyl ester of a branched monocarboxylic acid, wherein the monocarboxylic acid has from 5 to 50 carbon atoms, wherein said hydrolysis stabilizer is present in the film in the form of its reaction product with at least some of the end-groups of said polyester, and wherein said reaction product is obtained by the reaction of the hydrolysis stabilizer with the end-groups of the polyester in the presence of a metal cation selected from the group consisting of Group I and Group II metal cations.
    Type: Grant

  • Flame retardant polyester film
    Publication number: 20040097621
    Abstract: The use of copolyester of one or more dicarboxylic acid(s), one or more diol(s) and one or more copolymerisable phosphorous-containing flame retardant compound(s) wherein the phosphorus atom(s) are present in the copolyester in a group pendant to the polymer backbone, for the purpose of providing thermal stability and flame retardancy to an article made from said copolyester.
