    Abstract: Compounds comprising one or more functionalized fatty acid esters, which may be derived from bio-based oils, are used as a low-VOC coalescent agent (i.e., a coalescent agent having a low content of volatile organic compounds) in waterborne coating compositions. The functional group can be epoxide, vicinal diol, hydroxy phosphotriester, hydroxy ester, hydroxyl alkyl ester, hydroxyl benzyl ester, hydroxy ether, hydroxy amino, hydroxy sulfide, hydroxy nitrile, hydroxy amine, terminal alcohol, thiiran, ketone, or cyclic carbonate. The present disclosure also relates to waterborne coating compositions comprising these functionalized fatty acid esters.

    Abstract: A multiphase emulsion polymer for aqueous coating compositions containing little or no organic solvent includes at least one soft phase and at least one hard phase prepared by a multi-stage emulsion polymerization. The hard phase contains a hard phase polymer having a glass transition temperature in a range from I0 C to 100 C which is more than 50 C higher than that of the soft phase polymer. The hard phase is formed as a first stage polymer and the one soft phase is subsequently polymerized in the presence of the first stage polymer. The hard phase polymer includes at least one carboxylic acid monomer and at least one ethylenically unstaturated monomer. A method of making a multiphase emulsion polymer for aqueous coating compositions containing zero or low levels of organic solvent is disclosed. Such aqueous coating compositions may simultaneously have excellent block resistance, freeze thaw stability and low temperature coalescence characteristics.

    Abstract: Emulsion polymers and coating compositions made therefrom that exhibit exceptional stain resistance to both hydrophilic and hydrophobic stains. The emulsion polymers include, as polymerized units: a) at least one ethylenically unsaturated nonionic monomer in an amount ranging between about 85 wt. % to less than 100 wt. % based on the overall weight of the polymer composition; b) a first acid monomer in an amount ranging from about 0.1 to 2 wt. %, the first monomer being a strong acid monomer selected as a phosphorus-based acid monomer, a sulfur-based acid monomer, or a mixture thereof, and c) a second acid monomer in an amount ranging from about 0.1 to 2 wt. %, the second monomer being one or more ethylenically unsaturated monomers having at least one carboxyl or carboxylic anhydride functional group. The relative amounts of the first and second acid monomers are such that the ratio of b/c is greater than 0.7.
