  • Thermoplastic resin compositions suitable for use in transparent laminates
    Patent number: 7951865
    Abstract: The present invention is an improved polymeric resin composition comprising or consisting essentially of from about 70 wt % to about 79 wt % units derived from ethylene and from about 21 wt % to about 30 wt % units derived from an ?,?-unsaturated carboxylic acid having from 3 to 8 carbons. Resins of the present invention are particularly suitable for preparing transparent laminates useful as glazing elements that provide a greater measure of safety than non-laminated glazing elements. Laminates of the present invention have 3% haze or less without the addition of amines.
    Type: Grant

  • Thermoplastic resin compositions suitable for use in transparent laminates
    Publication number: 20070289693
    Abstract: The present invention is an improved polymeric resin composition comprising units derived from ethylene, from about 20 wt % to about 30 wt % units derived from an ?,?-unsaturated carboxylic acid having from 3 to 8 carbons, and optionally an effective amount of at least one additive selected from the group consisting of hindered amine light stabilizers, UV light absorbers, and thermal stabilizers. Resins of the present invention are particularly suitable for preparing transparent laminates useful as glazing elements that provide a greater measure of safety than non-laminated glazing elements.

  • Composition comprising nanoparticle TiO2 and ethylene copolymer
    Patent number: 7265176
    Abstract: Disclosed is a composition comprising or produced from nanoparticle-sized TiO2, an ethylene copolymer or ionomer of the ethylene copolymer, and optionally a second polymer. Also disclosed are films and other shaped articles produced therefrom. The composition, possessing a UV light barrier, can be used to protect the products that may be susceptible to UV such as foodstuffs.

  • Process for modifying visosity of ethylene copolymers
    Patent number: 5194516
    Abstract: The viscosity of copolymers of a) ethylene and C.sub.1 -C.sub.8 acrylate or methacrylates or b) ethylene, vinyl esters of C.sub.1 -C.sub.4 carboxylic acids, and another comonomer selected from the group consisting of carbon monoxide, acrylic acid, methacrylic acid, or a glycidyl ester of acrylic or methacrylic acid is increased, while maintaining gel content at a level of less than 3%, by treatment with a free radical generating agent.
