Method for preparing a UV curable coating composition
The present invention relates to a method comprising the steps of: a) contacting an acrylate monomer, a carboxylic acid monomer, and a chain transfer agent under free radical polymerization conditions to form a solution of a polymer having an M.sub.n in the range of from 5,000 to 50,000 Daltons; b) contacting the solution with a base and an ethylenically unsaturated glycidyl functionalized monomer to form a solution of an ethylenically unsaturated acrylate polymer; c) contacting the solution of the ethylenically unsaturated functionalized acrylate polymer with water to form an aqueous dispersion of ethylenically unsaturated functionalized acrylate polymers; and d) removing the organic solvent. The method of the present invention provides a composition suitable for use as a UV curable coating that achieves an excellent balance of hardness, flexibility, and warmth with less reliance on costly MFAs.

ACRYLIC POLYMERS, AQUEOUS POLYMERIC DISPERSIONS PREPARED THEREFROM, AND CURABLE FILM-FORMING COMPOSITIONS PREPARED THEREFROM
The present invention is directed to an acrylic polymer prepared from a reaction mixture comprising: (i) an ethylenically unsaturated monomer comprising hydroxyl functional groups; (ii) an ethylenically unsaturated monomer comprising polydialkylsiloxane groups; (iii) an ethylenically unsaturated monomer comprising carboxylic acid functional groups or amine functional groups; and (iv) a reactive diluent that is reactive with the ethylenically unsaturated monomer (iii). The reactive diluent (iv) is present initially in the reaction mixture as a medium in which the monomers polymerize. The present invention is further directed to aqueous polymeric dispersions prepared therefrom and aqueous, curable film-forming compositions prepared from the dispersions. The curable film-forming compositions are low VOC and are useful in methods of mitigating dirt build-up on a substrate.
