    Abstract: Disclosed are low Tg latex polymers and low VOC aqueous coating compositions having an improved open time profile, as well as drying time, stain resistance, wet edge time, low temperature film formation, block resistance, adhesion, water sensitivity and low-VOC content. The latex polymers and aqueous coating compositions include at least one latex polymer derived from at least one monomer copolymerized or alkoxylated compounds or blended with an alkoxylated compound, for example an alkoxylated tristyrylphenol or an alkoxylated tributylphenol. Also provided is an aqueous coating or adhesive composition including at least one latex polymer, water and one or a blend of two or more open time additives or drying time additives. The blend can comprise nonionic and anionic open time additives. Typically, the open time and/or drying time additive is present in an amount greater than about 1.3% by weight of the polymer or composition, typically in an amount greater than about 2% by weight of the polymer or composition, in an amount greater than about 4% by weight of the polymer or composition, in an amount greater than about 7.5% by weight of the polymer or composition, in an amount greater than about 10% by weight of the polymer or composition or in an amount greater than about 20% by weight of the polymer or composition.

    Abstract: Polymerizable ester surfactant, or a salt thereof, having the formula: R1—C(O)—R2—X wherein: R1 is an optionally substituted vinyl radical, R2 is a divalent polyoxyalkylene radical having at least two oxypropylene units, optional oxyethylene units in a block or random pattern, and a molar ratio oxypropylene units to oxyethylene units of at least about 2:1, preferably at least about 3:1, typically at least about 4:1 and more typically at least about 5:1, and X is a phosphate group, wherein in the ester the mono-phosphate ester to di-phosphate ester weight ratio is greater than 80:20. These polymerizable surfactant compounds are useful as the sole surfactant in producing polymer latices by emulsion polymerization by polymerization of them with another polymerizable monomer.
