  • Unsaturated polyester resin compositions and electrical laminates made therefrom
    Patent number: 4990397
    Abstract: An unsaturated polyester composition is provided comprising an unsaturate polyester component, a cross-linking monomer and as a modifier of the resin a polyoxyalkylene alcohol at least partially esterified with a polymerizable unsaturated carboxylic acid. The modifier is produced by esterifying the hydroxy group of a polyoxyalkylene mono- or polyalcohol at least partially with a polymerizable carboxylic acid such as a maleic acid.
    Type: Grant
    Filed: May 3, 1990
    Date of Patent: February 5, 1991
    Assignee: Kanegafuchi Kagaku Kogyo Kabushiki Kaisha

  • Unsaturated polyester resin compositions
    Patent number: 4710420
    Abstract: An unsaturated polyester resin composition is provided comprising a hard unsaturated polyester component, a soft unsaturated polyester component and a cross-linking monomer. The soft polyester component contains a polyoxyalkylene segment having a molecular weight from 600 to 6000 in the backbone thereof and is dispersed in the hard polyester component forming fine particles having a particle size not greater than 4 microns. The resin composition, when cured, exhibits a Tg corresponding to the hard polyester component from 100.degree. C. to 200.degree. C. and another Tg corresponding to the soft polyester component from -100.degree. C. to 0.degree. C.
