<p>PROCESS FOR THE MANUFACTURE OF PLASTICS DISPERSIONS of the disclosure: Plastics dispersions are described which impart high wet adhesion to paints formulated therewith. The dispersions are obtained by copolymerizing A) from 5 to 50 % by weight, preferably from 15 to 35 % by weight, relative to the total amount of monomers, of vinyl esters of saturated branched monocarboxylic acids having from 5 to 20, preferably from 5 to 11 carbon atoms, the carboxyl groups of which are directly linked to a tertiary or quaternary carbon atom, B) from 40 to 94.5 % by weight of vinyl acetate, vinyl propionate and/or vinyl isobutyrate, C) optionally from 0 to 30 % by weight of other alpha-beta-un-saturated compounds copolymerizable with the above monomers, and D) from 0.5 to 10 % by weight of an acetoacetic acid ester of the formula were X is -O-, -O-CH2- or -O-CH2-CH2-O-? and R and R' each are H or CH3.</p> |
