Abstract

The prodn. of low-viscosity aq. dispersions (PD') of water-soluble polymer with a mean mol. wt. of at least 500000 (A) and with a high concn. of active substance, comprises the polymerisation of (a1) 80-100 wt.% water-soluble monomer(s) and opt. (a2) 0-20 wt.% amphiphilic monomer(s) in presence of polymeric dispersant(s) (D), with removal of water.
