Title: ACRYLIC MODIFIED WATERBORNE SULFONATED ALKYD DISPERSIONS
Abstract:
A water-based latex of an acrylic-modified waterborne alkyd dispersion in water is described. The acrylic-modified waterborne alkyd is a hybrid resin prepared by the polymerization of at least one ethylenically unsaturated monomer in the presence of a waterborne alkyd having at least one pendant sulfonate functionality. The ethylenically unsaturated monomer may also be a latent oxidatively functional (LOF) acrylic monomer. Preparation of the latexes may be achieved by emulsion polymerization of at least one ethylenically unsaturated monomer in the presence of a waterborne alkyd having at least one pendant sulfonate functionality. Preparation of hybrid latexes which contain latent oxidative functional (LOF) acrylic monomers may also be achieved by emulsion polymerization of at least one LOF acrylic monomer in the presence of a waterborne alkyd having at least one pendant sulfonate functionality whereby the latent oxidative functionality of the acrylic polymer survives polymerization. Such acrylic-modified waterborne alkyds are useful in a variety of coating compositions.
