<p>Polymer obtained by precipitation polymerization process of a monomer mixture comprising (a) 30-99 wt.% of at least a non-ionic water-soluble monomer; (b) at least a monomer different from (a), which is at least one hydroxyl group carrying monomers and/or anionic monomers; (c) optionally at least an amino group carrying monomer; and (d) other optional monomers, where the monomer mixture contains less than 0.1 wt.% of a monomer with at least 2 radically polymerizable double bonds per molecule, in relative to the total quantity of (a), (b), (c) and (d), is new.</p> |
