  • Patent number: 6075089
    Abstract: The present invention concerns a process for producing dispersions of watsoluble vinyl polymers and a stabilizer for carrying out this process. Such water-soluble, particularly cationic vinyl polymers, are employed on a large scale as process expediters for carrying out, for instance, separating processes in water treatment or waste-water purification, respectively, in the paper, coal and ore industries, in oil production or also in the food stuff industry, among others, for floculation, coagulation, retention or dewatering. According to the present invention, water-soluble vinyl polymers are homo- or copolymerized in the presence of a dispersion stabilizer of the invention. The stabilizer consists of a graft copolymer whose backbone is formed by polyethylene oxide and its grafted branches of cationic vinyl monomers. Among others, cationic, hydrophobically modified vinyl monomers can be advantageously employed.
