Preparation of water soluble segmented polymers

摘要: Water-soluble segmented polymers of the ##STR1## A--B--A, and (A--B)n types wherein A-segments are grafted homopolymer, copolymer and/or terpolymer segments water-soluble vinyl monomers, B-segments homopolymer poly(vinyl pyrrolidone) or alcohol), prepared by a process employing inverse emulsion techniques cerium (IV) salt initiators.
