ABSTRACT:
Polymers in bead form are prepared from water-soluble ethylenically unsaturated monomers by a reverse suspension polymerization of a liquid in the presence of polymerization initiators and protective colloids obtainable by grafting polymers (A) containing (a) aromatic monovinyl monome from 40 to 100% by weight (b) C.sub.3-6 monoethylenically unsaturated carboxylic acid and/or maleic anhydride from 0 to 60% by weight (c) other monoethylenically unsaturated monomers from 0-20% by weight, as copolymerized units with the proviso that the sum of the weight (a) to (c) is always 100 and the polymer (A) has a molecular weight (number average) from 500 to 20,000 and a hydrogenation iodine number from 1.3 to 51 with a fixed monomer mixture at given concentration levels.
