Abstract: Production of low-emission dispersion paints, coating materials and synthetic resin dispersion plasters in the form of aqueous preparations based on aqueous synthetic resin dispersion copolymers derived from olefinically unsaturated monomers, having a pigment volume concentration (PVC) of at least 60% and containing water, fillers, pigments, synthetic resin dispersion copolymers and conventional auxiliaries, wherein the synthetic resin dispersion copolymers have a content of 0.05 to 2% by weight of monomer units derived from special unsaturated hydrolyzable organic silicon compounds and the aqueous copolymer dispersions possess a minimum film-forming temperature (MFT) of <10.degree. C. preferably <5.degree. C.and especially <2.degree. C., the aqueous preparations according to the invention contain <0.1% by weight of volatile non-aqueous constituents, based on the total non-volatile part of the preparations, and the pH of the aqueous preparations is in the range from 5.5 to 10.

Abstract: Vinyl esters can be polymerized, optionally together with further monomers, in the presence of emulsifiers and with the aid of radical-forming initiators in an aqueous medium at elevated temperature. The simultaneous presence of dispersing agents is advantageous. For the application of the dispersions obtained as coating material it is recommended to add to them after their preparation a water-soluble salt of a copolymer of styrene and a maleic acid derivative. The plastics dispersions so modified have a high pigment binding capacity and are suitable above all for the manufacture of dispersion paints and paper coating compositions.

Abstract: In the manufacture of plastics dispersions on the basis of vinyl polymers water-soluble salts of polybasic phosphonic acid derivatives, especially alkane-phosphonic acids and phosphonomethyl amines are used as dispersing auxiliaries. The dispersions obtained are suitable as coating agents and for impregnating, coating or glueing solid materials.

Abstract: Vinyl polymers are prepared by emulsion polymerization of olefinically unsaturated compounds in the presence of surface-active compounds. As emulsifiers there are particularly suitable water-soluble salts of alkane phosphonic acids or of alkane phosphonic acid-monoalkyl esters. Said salts may also be used in combination with other surface-active compounds. The plastics dispersion obtained is used above all as a binder for pigments and fillers in dispersion paints.

Abstract: Emulsifier-containing plastics dispersions which serve as a binder for dispersion paints, should contain polymers forming a film at room temperature and having a high wet adhesion. Suitable polymers are prepared by polymerization of olefinically unsaturated monomers initiated by free radical-forming agents, especially in the presence of an emulsifier. As emulsifier there is used a salt of an acyl ester of the hydroxymethane-phosphonic acid. The emulsifier may remain in the dispersion ready-for-use without involving disadvantages for the wet adhesion.
