ABSTRACT:
A polymeric composition comprising a polymer and less than about 1 weight percent surfactant is useful for producing a high-gloss latex paint. The polymer comprises about 25 to about 60 weight percent of a soft monomer whose homopolymer has a T.sub.g of less than about -20.degree. C. and about 40 to about 75 weight percent of a hard monomer whose homopolymer has a T.sub.g of greater than about 30.degree. C., and has a calculated T.sub.g of about 15.degree. to about 35.degree. C., an actual T.sub.g of about 10.degree. to about 60.degree. C., and a particle size of less than about 250 nm.
