Abstract
(DE)
Gegenstand der Erfindung sind wasserlösliche Copolymere auf Basis von a) 50 bis 97 Gew.-% an einem oder mehreren nichtionischen, ethylenisch ungesättigten Amidgruppen-haltigen Monomeren, b) 0,1 bis 10 Gew.-% an einem oder mehreren ethylenisch ungesättigten, Silangruppen-haltigen Monomeren c) 1 bis 30 Gew.-% an einem oder mehreren ionischen, ethylenisch ungesättigten Monomeren und gegebenenfalls einem oder mehreren weiteren ethylenisch ungesättigten Monomeren, wobei sich die Angaben in Gew.-% auf 100 Gew.-% aufaddieren.
(EN)
The invention relates to water-soluble copolymers based on a) 50 to 97 wt.% of one or more non-ionic monomers that contain ethylenically unsaturated amide groups, b) 0.1 to 10 wt.% of one or more monomers that contain ethylenically unsaturated silane groups, and c) 1 to 30 wt.% of one or more ionic, ethylenically unsaturated monomers and optionally one or more other ethylenically unsaturated monomers, the amounts in wt.% adding up to 100 wt.%.
(FR)
L'invention concerne des copolymères hydrosolubles à base a) de 50 à 97 % en poids d'un ou de plusieurs monomères non ioniques à insaturation éthylénique portant des groupes amide, b) de 0,1 à 10 % en poids d'un ou de plusieurs monomères à insaturation éthylénique portant des groupes silane et c) de 1 à 30 % en poids d'un ou de plusieurs monomères ioniques à insaturation éthylénique et éventuellement un ou plusieurs autres monomères à insaturation éthylénique, la somme des poucentages en poids indiqués étant égale à 100 % en poids.
