Abstract
A process for producing an aqueous copolymer dispersion is disclosed, which comprises emulsion polymerizing 100 parts by weight of a vinyl monomer mixture comprising (A) from 60 to 99.8% by weight of an acrylic ester of an aliphatic saturated alcohol having from 4 to 8 carbon atoms, (B) from 0.2 to 10% by weight of a monomer selected from the group consisting of an .alpha.,.beta.-unsaturated carboxylic acid, an .alpha.,.beta.-unsaturated carboxylic acid anhydride, a 2-hydroxyalkyl acrylate, a 2-hydroxyalkyl methacrylate, acrylamide, methacrylamide, methylolacrylamide, and methylolmethacrylamide, and (C) up to 30% by weight of a vinyl monomer other than the monomers (A) and (B) in the presence of from 0.01 to 10 parts by weight of a compound having an allyl hydrogen atom, with a total amount of the monomers (A), (B) and (C) being 100% by weight. The resulting aqueous copolymer dispersion can form a film which exhibits excellent adhesion performance particularly to an adherend having small polarity and gives off no smell.
