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.
