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.
Claims19
An emulsion of a copolymer of carbon monoxide with an olefinically unsaturated compound dispersed in an aqueous diluent which comprises water for at least 50% by weight of the aqueous diluent wherein the aqueous diluent and the copolymer are present in a weight ratio in the range of 1:2 to 5:1.
An emulsion of a copolymer of carbon monoxide with an olefinically unsaturated compound dispersed in an aqueous diluent which comprises water for at least 50% by weight of the aqueous diluent and a non-ionic surfactant wherein the surfactant is a graft surfactant which is obtained by grafting a polymer comprising a poly(ethene oxide) moiety and a primary amino group onto a copolymer of carbon monoxide with an olefinically unsaturated compound.
An emulsion of a copolymer of carbon monoxide with an olefinically unsaturated compound dispersed in an aqueous diluent which comprises water for at least 50% by weight of the aqueous diluent and a non-ionic surfactant which comprises in its molecular structure a hydrophilic moiety which is a poly(ethene oxide) block having a number average molecular weight of more than 1,000 and a lypophilic moiety which is a lypophilic polymer block having a number average molecular weight of more than 800 wherein the amount of surfactant present is in the range of 0.1-10% by weight, relative to the weight of the copolymer having been dispersed.
