ABSTRACT:
Aqueous polyacrylate dispersions having improved flow characteristics are prepared by polymerizing esters of acrylic acid and/or methacrylic acid and alkanols of 1 to 10 carbon atoms, with or without admixture of styrene and/or vinyl esters and/or water-soluble monoolefinically unsaturated comonomers (the monomer feed being in the form of an emulsion), in aqueous emulsion in the presence of a free radical polymerization initiator, a protective colloid, a nonionic emulsifier and a regulator, at least a part of the protective colloid being introduced into an aqueous initial charge, and a water-soluble regulator being employed in the initial charge and in the feed.
