Abstract: The invention provides new compounds which are cyclic alkylene ureas produced by the reaction of an alkylene urea selected from the group consisting of a mono-(alkylene ureido alkyl) urea, a bis-(alkylene ureido alkyl) urea, and mixtures thereof, with an unsaturated glycidyl ether or ester, such as allyl glycidyl ether. The new compounds are monomers which may be incorporated in aqueous emulsion polymer systems and are useful as wet adhesion promoters for latex paints.

Abstract: The invention provides new compounds which are cyclic alkylene ureas having hydroxyl and amine functionalities and which are produced by the reaction of an omega-amino alkyl alkylene urea, such as 2-aminoethyl ethylene urea, with an unsaturated glycidyl ether or ester, such as allyl glycidyl ether. The new compounds are monomers which may be incorporated in aqueous emulsion polymer systems and are useful as wet adhesion promoters for latex paints.

Abstract: Air-curing copolymer latices are described. The preferred copolymer latices are prepared by emulsion copolymerization, in the presence of a free radical polymerization catalyst such as inorganic or organic peroxide polymerization catalysts, with a blend (in % by weight based on the total weight of all monomers used) of (a) about 1% to about 20% of dicyclopentadienyl acrylate or dicyclopentadienyl methacrylate, (b) about 99% to about 20% of an alkyl acrylate or methacrylate, including mixtures of such monomers, and preferably a lower alkyl acrylate or methacrylate in which the alkyl groups contain from 1 to 4 carbon atoms, (c) 0% to about 5% of acrylic acid or methacrylic acid, and (d) 0% to about 85% of other monoethylenically unsaturated copolymerizable monomers.

Abstract: Novel emulsifiable prepolymers for polyurethanes comprising an isocyanate prepolymer a minor proportion of the terminal isocyanate groups of which have been reacted with a quaternized tertiary amino alcohol, storage stable polyurethane latices produced therefrom and methods of making them are described. In a preferred embodiment a conventional isocyanate terminated prepolymer is first produced by the reaction of a polyol, preferably a diol of polyether or polyester origin, with a stoichiometric excess of a polyisocyanate, preferably a diisocyanate such as toluene diisocyanate; this prepolymer is then reacted, under anhydrous conditions, with a small amount, usually from about 1% to 5%, preferably about 1% to about 2%, by weight of a quaternized tertiary amino alcohol. Alternatively, a small amount of the quaternized tertiary amino alcohol may be included in the mixture of polyol and excess isocyanate used for making the prepolymer.
