The reaction of unsaturated carbonates such as vinyl ethylene carbonate with N-aminoethylimidazolidone (TAM) under mild conditions generates a mixture of two vinyl and hydroxy functional imidazolidone carbamates which polymerize readily into acrylate or vinyl acetate based emulsion polymers. The polymers show enhanced wet adhesion (wet scrubbability) in latex paints and coatings.

There is claimed herein an aqueous emulsion comprising a functionalized organic polymer formed by mixing (a) a preformed aqueous emulsion comprising water, particles containing a plurality of silanol modified organic polymer molecules dispersed in the water, and a surfactant; (b) a functionalizing silane and (c) a tin catalyst. Depending on reaction conditions, these emulsions are predominantly non-precrosslinked and photocurable compositions that are crosslinked after application in either the wet or dry state.
