Abstract:
A method for formulating an aqueous dispersion of polymer comprising the steps of:a) providing a polymer solution containing hydrophobic acrylic polyol dissolved in a solvent, said hydrophobic acrylic polyol containing 5% to 50% by weight of an alkyl acrylate, 5% to 50% by weight hydroxyalkyl acrylate, 5% to 50% by weight alkyl methacrylate, and 5% to 50% by weight of vinyl aromatic compound;b) adding a surfactant selected from the group consisting of anionic, cationic, non-ionic and amphoteric surfactants to the polymer solution; andc) adding water to the polymer solution sufficient to form a dispersion of the polymer in the water.
