Abstract: Provided is a low volatile organic content (VOC), isocyanate based curable oil-in-water emulsion of a polyisocyanate crosslinker and a surface active isocyanate reactive material in an aqueous medium, and a process for the preparation thereof. Also provided is a water-in-oil intermediate product to which an aqueous medium can be added to produce the curable oil-in-water emulsions. Such curable emulsions are particularly suited for use in coatings applications.

Abstract: Provided is a non-aqueous, emulsifiable composition which, in its overall concept, comprises a substantially homogenous mixture of an unblocked polyisocyanate crosslinking agent and a surface active isocyanate reactive material. Also provided is a substantially homogeneous, curable, oil-in-water emulsion produced by, as well as a method of producing such by, the steps of admixing the components of the non-aqueous emulsifiable composition as described above and, thereafter, contacting such emulsifiable composition and an aqueous medium in proportions and under conditions so as to result in a substantially homogeneous, oil-in-water emulsion. Such curable emulsions find particular use in a variety of coatings applications.

Abstract: Substantially alternating, organic solvent soluble copolymers of 2000 to 4000 molecular weight useful as crosslinking agents and containing monomeric units derived from monomers comprising (i) 40 to 50 mole percent of an isopropenyl-.alpha.,.alpha.-dimethylbenzyl isocyanate, and (ii) 60 to 45 mole percent of an unsaturated ester are described together with processes for their preparation. Curable compositions containing the copolymer and an isocyanate reactive material are also described.
