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.
Claims17
In a polymerizable monomer formed by the reaction of an unsaturated moiety with a wet adhesion promoting moiety, the improvement which comprises 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.
14 The emulsion of claim 13 wherein the comonomers polymerized with the wet adhesion monomer are selected from the group consisting of acrylic esters derived from alcohols of 1 to 8 carbon atoms, vinyl acetate, vinyl decanoate and vinyl chloride.
The emulsion of claim 14 wherein the comonomers are selected from the group consisting of methyl methacrylate, butyl acrylate, and 2-ethylhexyl acrylate.
