Abstract
Freeze-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.
