An improved process for the preparing a dispersions of water soluble cationic polymers in an aqueous salt solution is disclosed. The improvement comprises using as a polymeric dispersion stabilizer a water soluble hydrophobically associating copolymer of diallyldimethylammonium chloride and a monomer selected from the group consisting of: <IMAGE> (III) and alkyl esters of acrylic acid, where R1 is either hydrogen or CH3; R2 and R3 are each an alkyl group having 1 to 3 carbon atoms; A1 is either an oxygen atom or NH; B1 is either an alkylene group having 2 to 4 carbon atoms or a hydroxypropylene group, Q is benzyl, or C6-C20 alkyl, and X1- is an anionic counterion. |
