HOE 78/F 102 AQUEOUS PLASTICS DISPERSION ON THE BASIS OF VINYL ESTER POLYMERS, PROCESS FOR THE MANUFACTURE THEREOF, AND COATING MATERIAL MADE THEREFROM Abstract of the disclosure: 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 re- commended 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.
