Abstract
An aqueous plastics dispersion is manufactured by copolymerization of several olefinically unsaturated monomers, one of them at least being free from amide and sulfo groups, one of them at least having an amide group and one of them at least having a sulfo group. Copolymerization is carried out in an aqueous medium under usual conditions. The resulting copolymer has a second order transition temperature of 20.degree. C. at most. The plastics dispersion is compatible with cement and serves as additive in cement-containing building materials.
