International ClassesC08L 031/02C08L 033/02 AbstractFreeze-thaw stable latex binders and latex paint compositions are prepared without the use of volatile freeze-thaw additives. The latex binder contains a polymer which is the emulsion polymerization product of a polymerizable polyethylene glycol (PPEG) monomer, wherein the molecular weight of the ethylene oxide moiety in the PPEG monomer is from about 175 to 1,100, at least one acrylic monomer and, optionally, one or more styrenic, ionic or wet adhesion monomers. Methods for preparing the freeze-thaw stable latex compositions are also disclosed.Field of SearchMonomer contains chalcogen other than in C(=O)-O- chalcogen in any monomer)Hydroxyl group Ether or hydroxy containing Acid or ester contains an oxygen atom which is other than part of a free carboxyl group or carboxylic acid ester group Two or more carboxylic acids or derivatives Polymerizing in the presence of water and in the presence of a solid polymer derived from ethylenic reactants only Solid polymer utilized is derived from an unsaturated carboxylic acid or salt | |
