Abstract
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.
