Abstract:
(EN) Finely divided, cationic, aqueous polymer dispersion which is obtainable by emulsion polymerisation of ethylenically unsaturated monomers in an aqueous liquid containing a cationic prepolymer as a dispersant, wherein the cationic prepolymer is prepared in the presence of at least one polymerisation initiator by polymerisation of (a) from 15 to 45% by weight of at least one ethylenically unsaturated monomer comprising at least one quaternary ammonium group; (b) from 5 to 80% by weight of at least one optionally substituted styrene; (c) from 0 to 50% by weight of at least one C1-12 alkyl (meth) acrylate; (d) from 0 to 10% by weight of at least one ethylenically unsaturated monomer comprising an acid group; (e) from 0 to 10% by weight of at least one ethylenically unsaturated monomer comprising an amine group; and (f) from 0 to 20% by weight of at least one non-ionic ethylenically unsaturated monomer differing from (b), (c) and (e), the sum of (a) + (b) + (c) + (d) + (e) + (f) being 100% by weight, in a first emulsion polymerisation in the presence of at least one non-ionic emulsifier, and thereafter, in the aqueous liquid containing the cationic prepolymer, a second emulsion polymerisation is carried out, in the presence of at least one polymerisation initiator, of a monomer mixture comprising (i) from 10 to 70% by weight of at least one of an optionally substituted styrene or (meth) acrylonitrile; (ii) from 30 to 90% by weight of at least one CMS alkyl (meth) acrylate; (iii) from 0 to 30% by weight of at least one vinyl ester of linear or branched C1-30 carboxylic acids; and (iv) from 0 to 30% by weight of at least one non-ionic ethylenically unsaturated monomer differing from (i), (ii) and (iii), the sum of (i) + (ii) + (iii) + (iv) being 100% by weight, and the first emulsion polymerisation and/or the second emulsion polymerisation is optionally carried out in the presence of from 0 to 10% by weight of at least one polymerisation regulator. The polymer dispersions according to the present invention are suitable for use as sizing agents for paper, board and cardboard.
(FR) L'invention concerne une dispersion aqueuse, cationique, finement divisée de polymères, pouvant être obtenue par polymérisation en émulsion de monomères éthyléniquement insaturés dans un liquide aqueux contenant un prépolymère cationique en tant que dispersant, le prépolymère cationique étant préparé en présence d'au moins un initiateur de polymérisation par polymérisation de (a) 15 à 45 % en poids d'au moins un monomère éthyléniquement insaturé comprenant au moins un groupe d'ammonium quaternaire ; (b) 5 et 80 % en poids d'au moins un styrène éventuellement substitué ; (c) 0 à 50 % en poids d'au moins un (méth)acrylate d'alkyle en C1-12 ; (d) 0 à 10 % en poids d'au moins un monomère éthyléniquement insaturé comprenant un groupe acide ; (e) 0 à 10 % en poids d'au moins un monomère éthyléniquement insaturé comprenant un groupe amine ; et (f) 0 à 20 % en poids d'au moins un monomère éthyléniquement insaturé non ionique différent de (b), de (c) et de (e), la somme de (a) + (b) + (c) + (d) + (e) + (f) valant 100 % en poids, dans une première polymérisation en émulsion en présence d'au moins un émulsifiant non ionique, puis, dans le liquide aqueux contenant le prépolymère cationique, une deuxième polymérisation en émulsion étant effectuée en présence d'au moins un initiateur de polymérisation, d'un mélange de monomères comprenant (i) 10 à 70 % en poids d'au moins un styrène ou (méth)acrylonitrile éventuellement substitué ; (ii) 30 à 90 % en poids d'au moins un (méth)acrylate d'alkyle en C1-16 ; (iii) 0 à 30 % en poids d'au moins un ester vinylique d'acides carboxyliques linéaires ou ramifiés en C1-30 ; et (iv) 0 à 30 % en poids d'au moins un monomère éthyléniquement insaturé non ionique différent de (i), de (ii) et de (iii), la somme de (i) + (ii) + (iii) + (iv) valant 100 % en poids, et la première polymérisation en émulsion et/ou la deuxième polymérisation en émulsion étant éventuellement réalisée(s) en présence de 0 à 10 % en poids d'au moins un régulateur de polymérisation.
