Beschreibung
Zusammenfassung:	Water-soluble comb-type branched cationic acrylamide copolymers of formula (I) with high mol. wt., which have side chains formed by acrylamide and a main chain formed by linear cationic prepolymer (II) contg. amino gps., are new; and are prepd. by a special inverse emulsion polymerisation process, in which an initial stabilised oil-in-water emulsion is converted to a water-in-oil emulsion during polymerisation by adding an inverse emulsion of the water-soluble initiator in oil or by separate addn. of an aq. soln. of the initiator and a soln. of a low HLB wetting agent in oil.
