    摘要: The invention relates to a method of manufacturing dispersions of water-sble cationic vinyl polymers which can be used as process aids for separation processes, e.g. as flocculation aids, coagulation agents, retention agents or dehydration accelerators. The dispersions are produced by radical homopolymerization of cationic, hydrophobically modified vinyl monomers or their copolymerization with water-soluble vinyl monomers in aqueous saline solutions. In this respect block copolymers are used as dispersion stabilizers, and which are formed from a cationic vinyl monomer and ethyleneoxide.
