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.
