Abstract

A method of recovering a solid water-insoluble polymer or copolymer of an alpha-beta-ethylenically unsaturated aldehyde from an aqueous dispersion comprises adjusting the pH of the aqueous dispersion to a value not higher than 7, passing the resulting dispersion along an elongated path in a heating zone whereby the liquid component of the slurry is vaporized and the mixture is connected into a suspension of polymer particles in the vapour stream, passing the vaporous suspension into a solid removal device whereby the solid polymer is recovered as a dry powder. The solid removal device is preferably a cyclone vessel. The aqueous dispersion may also contain a water-insoluble organic hydrocarbon. The monopolymer or copolymers are obtained by conventional polymerization.
