  • 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.

  • Laminated structures with superior impact resistance and process for making same
    Patent number: 7214433
    Abstract: The present invention is a laminate article comprising at least three layers of plasticized polyvinylbutyral (PVB) sheet, wherein at least one layer of the laminate is a stiff PVB sheet and at least two layers are soft PVB sheets. A laminate article of the present invention is useful for providing increased protection from damages occurring to automobiles, buildings, and windows by virtue of exposure of same to, for example, hurricane force winds, impact from debris propelled by high-force winds, or by intentional impact against windows comprising the laminates of the present invention.
