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.
Claims7
In an emulsion incorporating a polymeric component suited for use in forming paints and coatings having wet adhesion promoting monomer units polymerized therein, said wet adhesion promoting polymer formed by emulsion polymerizing ethylenically unsaturated compounds with an ethylenically unsaturated wet adhesion promoting moiety to form said polymeric component, the improvement which comprises incorporating a polymerizable monomer formed by the reaction of a carbonate selected from the group consisting of vinyl ethylene carbonate, methacryloxypropylene carbonate and allyloxypropylene carbonate and a wet adhesion promoting moiety selected from the group consisting of an alkyl urea and a cyclic urea.
