ABSTRACT:
There is provided a process for preparing polyelectrolytes by a water-in-oil emulsion process. A water-in-oil azeotropic emulsion is heated with agitation and a concentrated aqueous solution of small amounts of a polymerization initiator and gel inhibitor and at least one water-soluble vinyl monomer adapted to polymerize at reflux temperature with a concomitant loss of water by azeotropic distillation is added thereto to polymerize said water-soluble monomer.
The polymerized product including a gel inhibitor forms a gel-free aqueous solution.
