Abstract (en)
[origin: WO2007082868A1] The present invention relates to processes for preparing polymers which contain 50-95% by weight of at least one ester of (meth)acrylic acid, 5-50% by weight of at least one olefinically unsaturated, free-radically polymerizable anionogenic or anionic compound and from 0 to 30% by weight of at least one further free-radically polymerizable compound in copolymerized form, by free-radical polymerization in a solution comprising alcohol, wherein the polymerization initiator used is at least one water-soluble initiator.
