Title (EN) AQUEOUS POLYMER DISPERSIONS
(FR) DISPERSIONS AQUEUSES DE POLYMÈRE
Abstract:
(EN) An aqueous polymer dispersion is produced by multistage emulsion polymerization, in which a monomer composition I comprising 19 to 29 wt% hard monomers and 64 to 74 wt% soft monomers is polymerized to produce a first polymer phase and then a monomer composition II comprising 65 to 95 wt% hard monomers and 5 to 35 wt% soft monomers is polymerized to produce a second polymer phase. Monomer composition I also comprises from 1 to 5 wt% of at least one monomer selected from ethylenically unsaturated sulfonic acids, phosphonic acids, phosphoric acids, carboxylic acids, carboxylic amides, carboxylic anhydrides and mixtures thereof and 1 to 7.5 wt% of ethylenically unsaturated monomers containing keto groups. The weight ratio of monomer composition I to monomer composition II ranges from 50:50 to 65:35 and the polymer dispersion also contains a water-soluble cross-linking component selected from polyfunctional carboxylic hydrazides and/or polyfunctional amines.
(FR) L'invention concerne une dispersion aqueuse de polymère produite par polymérisation en émulsion à plusieurs étages, dans laquelle une composition de monomères I comprenant 19 à 29 % en poids de monomères durs et 64 à 74 % en poids de monomères mous est polymérisée pour produire une première phase polymère, puis une composition de monomères II comprenant 65 à 95 % en poids de monomères durs et 5 à 35 % en poids de monomères mous est polymérisée pour produire une deuxième phase polymère. La composition de monomères I comprend également 1 à 5 % en poids d'au moins un monomère choisi parmi les acides sulfoniques, les acides phosphoniques, les acides phosphoriques, les acides carboxyliques, les amides carboxyliques, les anhydrides carboxyliques, éthyléniquement insaturés, et les mélanges correspondants et 1 à 7,5 % en poids de monomères éthyléniquement insaturés contenant des groupes céto. Le rapport en poids de la composition de monomères I à la composition de monomères II se situe dans la plage de 50:50 à 65:35 et la dispersion de polymères contient également un constituant de réticulation soluble dans l'eau choisi parmi les hydrazides carboxyliques polyfonctionnels et/ou les amines polyfonctionnelles.
