  • Aqueous polymer emulsion
    Patent number: 5843580
    Abstract: An emulsion of a copolymer of carbon monoxide with an olefinically unsaturated compound dispersed in an aqueous diluent; a curable resin composition in the form of an oil-in-water emulsion comprising a copolymer of carbon monoxide with an olefinically unsaturated compound and a curing agent; and a process for producing a laminated wood composite comprising applying said curable resin composition onto wood parts of the composite, bringing the wood parts of the composite together such that curable resin composition is positioned between adjacent wood parts, and curing the curable resin such that after curing cured resin adheres adjacent wood parts to one another.
    Type: Grant
    Filed: July 9, 1997
    Date of Patent: December 1, 1998
    Assignee: Shell Oil Company
