Abstract: Aqueous dispersions of copolymers consisting of 50-99.9% by weight of a vinyl ester of a saturated monocarboxylic acid having from 1 - 18 carbon atoms, 0.1 - 15% by weight of an alpha -haloalkane carboxylic acid vinyl ester of the formula wherein R1 is hydrogen, a halogen atom or an alkyl radical having 1 - 16 carbon atoms, R2 is hydrogen, a halogen atom or an alkyl radical having 1 - 13 carbon atom and X is a halogen atom, and 0 - 49.9% by weight of at least one other ethylenically unsaturated monomer which can be cross-linked while drying with 0.05% to 10% by weight calculated on the total mixture of an aminoplast resin, a polyamine, a polyamidoamine or a mixture of Formaldehyd and ammonia or an amine. The mixture of the dispersion and the cross-linking agent is stable, and cross-linking will start only when the mixture is applied to a substrate such as a fiber.

Abstract: Vinyl acetate/ethylene copolymer powders are obtained by spray-drying of the corresponding aqueous polymer dispersions while simultaneously adding finely divided inorganic materials as anti-caking agents. The polymer powders thus obtained have an excellent storage stability, are easily dispersible in water and yield plastics mortars of high water resistance and plasterings made therefrom which are free from cracks.
