Abstract: Disclosed are latex polymers and an aqueous coating compositions having excellent freeze-thaw stability, open time, stain resistance, low temperature film formation, foam resistance, block resistance, adhesion, water sensitivity and a low-VOC content. The latex polymers and aqueous coating compositions include at least one latex polymer derived from at least one monomer copolymerized or blended with an alkoxylated compound, for example an alkoxylated tristyrylphenol or an alkoxylated tributyiphenol. Also provided is an aqueous coating composition including at least one latex polymer, at least one pigment, water and at least one freeze-thaw additive. Typically, the freeze-thaw additive in an amount greater than about 1.3% by weight of the polymer, typically in an amount greater than about 2% by weight of the polymer, in an amount greater than about 4% by weight of the polymer, in an amount greater than about 7.5% by weight of the polymer, in an amount greater than about 10% by weight of the polymer or in an amount greater than about 20% by weight of the polymer.
