Abstract

Procédé pour la préparation de polymères ou copolymères à partir d'esters vinyliques et/ou d'esters d'acides carboxyliques. Dans ce procédé, le mélange réactionnel contenant les esters en question, un système réducteur, un système oxydant, un agent de transfert de chaîne, un colloïde protecteur et un tensio-actif, est polymérisé en chargeant tous les ingrédients sauf le système oxydant et une partie des esters concernés, à une température qui ne dépasse pas 80 degrés C, puis en ajoutant le reste de l'ester et du système oxydant. Les émulsions ainsi obtenues ont de meilleures propriétés que les émulsions de l'art antérieur. Ces polymères et copolymères sont surtout utilisés par l'industrie des adhésifs.Process for the preparation of polymers or copolymers from vinyl esters and / or esters of carboxylic acids. In this process, the reaction mixture containing the esters in question, a reducing system, an oxidizing system, a chain transfer agent, a protective colloid and a surfactant, is polymerized by charging all the ingredients except the oxidizing system and a part of the esters concerned, at a temperature not exceeding 80 degrees C, then adding the rest of the ester and the oxidizing system. The emulsions thus obtained have better properties than the emulsions of the prior art. These polymers and copolymers are mainly used by the adhesive industry.
