Title (EN) DISPERSANTS FOR EMULSION PAINTS
(FR) DISPERSANTS POUR PEINTURES-EMULSION
Abstract:
(EN) A pigment dispersant, for instance for incorporation in an emulsion paint containing non-reactive or reactive pigment, is a water-soluble copolymer of monomer units derived from two or more monomers of the formula CH2 = CR1 - COOR2 wherein R1 is methyl in 75 to 85 mol % of the monomer units and is hydrogen in the remainder, and R2 is hydrogen or a cation in 75 to 85 mol % of the monomer units and is C1-8 alkyl in the remainder of the monomer units and wherein at least 80 % of the R2 alkyl groups are butyl groups.
(FR) La présente invention concerne un dispersant pigmentaire destiné à être incorporé, par exemple, dans une peinture-émulsion contenant un pigment réactif ou non-réactif. Ce dispersant est un copolymère hydrosoluble d'unités monomères dérivées d'au moins deux monomères représentés par la formule CH2 = CR1 - COOR2. Dans cette formule, R1 est méthyle pour 75 à 85 % des moles des unités monomères et hydrogène pour le reste. R2 est hydrogène ou un cation pour 75 à 85 % des moles des unités monomères et alkyle C1-8 pour le reste des unités monomères, 80 % au moins des groupes alkyle de R2 étant des groupes butyle.
