Abstract: Emulsion polymers and coating compositions made therefrom that exhibit exceptional roller stability and stain resistance to both hydrophilic and hydrophobic stains, without sacrificing scrub resistance. The emulsion polymers include, as polymerized units formed at a pH between 3 and 9:



a) at least one nonionic or anionic unsaturated monomer in an amount ranging between about 78 wt. % to less than 100 wt. % based on the overall weight of the polymer composition
b) one or more strong acid monomer in an amount ranging from about 0.01 wt. % to 2 wt. % based on the overall weight of the polymer composition; and
c) at least one lower alkyl acrylate monomer in an amount ranging between about 1 wt. % to 20 wt. % based on the overall weight of the polymer composition.

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.
