| description | The disclosed technology concerns a method for wetting and dispersing a pulverulent polycarboxylic acid containing polymer in aqueous media without the need of a steric stabilizer and/or a wetting agent, said method comprises a) providing a pulverulent pre-neutralized carboxylic acid containing polymer or copolymer, wherein said polymer or copolymer is prepared from a monomer mixture comprising at least one olefinically unsaturated carboxylic acid group containing monomer, and wherein from about 1 to about 10 wt.% of said carboxylic acid group containing monomer(s) is neutralized; b) mixing said pulverulent pre-neutralized carboxylic acid containing polymer or copolymer in aqueous medium; and c) mixing a deswelling agent selected from an acid, a salt, and combinations thereof with said aqueous medium, and optionally d). adjusting the pH.
L'invention concerne un procédé pour le mouillage et la dispersion d'un polymère contenant un acide polycarboxylique pulvérulent dans des milieux aqueux sans nécessiter un stabilisant stérique et/ou un agent mouillant, ledit procédé comprenant a) se procurer un polymère ou copolymère contenant un acide carboxylique pré-neutralisé pulvérulent, ledit polymère ou copolymère étant préparé à partir d'un mélange de monomères comprenant au moins un monomère contenant un groupe acide carboxylique à insaturation oléfinique, et d'environ 1 à environ 10 % en poids dudit ou desdits monomères contenant un groupe acide carboxylique étant neutralisés ; b) mélanger ledit polymère ou copolymère contenant un acide carboxylique pré-neutralisé pulvérulent dans un milieu aqueux ; et c) mélanger un agent de dégonflement choisi parmi un acide, un sel et des combinaisons de ceux-ci avec ledit milieu aqueux et facultativement d) ajuster le pH. |
