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.
