Abstract
An aqueous emulsion copolymer of monoethylenically unsaturated monomers which provide a copolymer having a glass transition temperature below 20.degree. C., is modified to include from about 0.3% to about 10% of a monoethylenically unsaturated copolymerizable polyether containing a chain of from about 6 to about 150 C.sub.2 -C.sub.4 oxyalkylene groups, the terminal hydroxy group provided by said chain of oxyalkylene groups being capped with a monofunctional hydrophobic group. These polyethers improve the brush drag of paints made with the emulsion copolymers, and in some instances the leveling is simultaneously improved.
