Abstract
Process for the preparation of aqueous dispersions of vinyl acetate and/or ethylacrylate polymer and/or higher vinyl esters for use in paper coating compositions together with pigments, natural binders, such as casein, starch, characterized in that they are polymerized in a mixture 70 - 95% by weight of vinyl acetate with 5 - 30% by weight of ethylacrylate and/or vinyl esters of monocarboxylic acids with up to 12 c atoms, 0 - 5% by weight of vinylsulfonic acid and/or styrenesulfonic acid, in what as an emulsifier, a mixture of I) 5-95% by weight of an aromatic hydroxy compound, alkylated with straight or branched hydrocarbon chain with 6-20 atoms of 20 which, per mole, were reacted with, 2-8 moles of ethylene oxide or with oxide of propylene and then sulfated, Ii) 0-95% by weight of an aromatic hydroxy compound, alkylated with straight or branched hydrocarbon chain, with 6-20 c atoms, which was reacted per mole with 1 - 40 moles of ethylene oxide or with propylene oxide, Iii) 0-95% by weight of a compound of the general formula ** (see formula) ** Where a = 2 - 40, b = 6 - 35 and c = 2 - 40, in which the sum of the emulsifiers results in 100% by weight, and a redox system is used as a polymerization catalyst.
