Abstract

Process for the preparation of highly viscous and stable aqueous vinyl polyester dispersions with a particle size of 0.03 to 0.2 μ by radical polymerization in aqueous phase of straight or branched chain carboxylic acid vinyl esters with 2 to 18 carbon atoms and optionally other ethylenically unsaturated monomers up to a weight ratio of 60%, based on the total amount of monomers, at a temperature of 10 to 100ºC, in the presence of alcoholic polyoxides or derivatives of alcoholic polyoxide with 5 to 50 ethylene oxide units per molecule and optionally anionic emulsifiers, characterized in that 5 to 25% by weight, preferably 8 to 20% by weight of the total amount of monomers in the presence of the emulsifier solution, polymerize to a degree of transformation of at least 70% by weight of the previously disposed monomer and are then metered in Continue the remaining monomers and a mixture of 0.1 to 2% by weight of acrylic, methacrylic or crotonic acid as well as 0.1 to 2% by weight of acrylic, methacrylic or crotonic acid amide, always referring to the total weight of the vinyl polyester dispersion, such that the monomer content of the reaction mixture does not exceed 25% by weight, preferably 15% by weight, based on the reaction mixture.
