Title (EN) AQUEOUS POLYMER DISPERSION
(FR) DISPERSION AQUEUSE DE POLYMÈRE
Abstract:
(EN) The invention relates to aqueous polymer dispersions, comprising a water insoluble polymer P in the form of dispersed polymer particles, which is obtainable by free radical aqueous emulsion polymerization of ethylenically unsaturated monomers M, which comprise a) at least one monomer M1 which exhibits two ethylenically unsaturated moieties which are connected by a linker which comprises a disulfide moiety, and b) at least one monoethylenically unsaturated monomer M2, which has a low water solubility. The invention also relates to processes for preparing such an aqueous polymer dispersion, to solid polymer compositions in powder form, obtainable by drying such polymer dispersions, to the use of such polymer dispersions in a coating material, adhesive or sealant and to a methods of coating a surface of a substrate which comprises applying an aqueous coating composition, which contains such an polymer dispersion.
(FR) L'invention concerne des dispersions aqueuses de polymère, comprenant un polymère P insoluble dans l'eau sous forme de particules polymères dispersées, qui peut être obtenu par polymérisation radicalaire en émulsion aqueuse de monomères à insaturation éthylénique M, qui comprennent a) au moins un monomère M1 qui présente deux fractions à insaturation éthylénique qui sont reliées par un lieur comprenant une fraction disulfure, et b) au moins un monomère à insaturation éthylénique M2, qui présente une faible solubilité dans l'eau. L'invention concerne également des procédés de préparation de cette dispersion aqueuse de polymère, des compositions polymères solides sous forme de poudre, pouvant être obtenues par séchage de ces dispersions de polymère, l'utilisation de ces dispersions de polymère dans un matériau de revêtement, un adhésif ou un matériau d'étanchéité, et un procédé de revêtement d'une surface d'un substrat qui comprend l'application d'une composition de revêtement aqueuse, qui comporte cette dispersion de polymère.
