ABSTRACT:
Polymers in powder form are manufactured by polymerizing water-soluble ethylenically unsaturated monomers, which form hydrophilic polymers, in a powder bed of polymers of water-soluble ethylenically unsaturated compounds in the presence of polymerization initiators and water as an auxiliary liquid, the water being entirely or partially removed from the polymerization zone by evaporation during the polymerization.
