METHOD OF MANUFACTURING DISPERSIONS OF WATER-SOLUBLE VINYL POLYMERS AND STABILISER FOR CARRYING OUT THE METH0D

摘要

The invention relates to a process for producing dispersions of water-soluble cationic vinyl polymers usable as process auxiliaries for separation processes, e.g. as flocullating auxiliaries, coagulants, retention agents and dewatering accelerators. The dispersions are produced by the radical homopolymerisation of cationic, hydrophobically modified vinyl monomers or their copolymerisation with water-soluble vinyl monomers in aqueous salt solutions. Block copolymers of a cationic vinyl monomer and ethylene oxide are used in this process as dispersion stabilisers.
