摘要

AQUEOUS VINYL ESTER COPOLYMER DISPERSIONS CAPABLE OF BEING CROSS-LINKED 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 O - 49.9 % by weight of at least one other ethylenically unsaturated monomer 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 as a fiber.
