Abstract: A continuous free radical polymerization process for the preparation of water-soluble copolymers from water-soluble monomers for further processing to dry polymers is disclosed. The process allows efficient polymerization of the monomers in aqueous solution in the presence of a free radical catalyst through backmixing. Water-soluble polymers with molecular weights of from about 3,000-30,000,000 and preferably from about 500,000-10,000,000 are obtained utilizing this process.

Abstract: The inventors have discovered a new method of treating paper machine white water aqueous systems and surfaces in the paper machine white water aqueous systems that prevents or inhibits the adhesion of bacterial cells to the surfaces and thereby controls the biological fouling of the surfaces. The process comprises adding to the aqueous system an adhesion-inhibiting amount of vinyl cationic polymer. This method effectively inhibits the adhesion of the bacterial cells to exposed surfaces without killing the fouling organisms and also without harming non-target organisms. In addition, the method of the present invention advantageously does not cause the formation of harmful substances in the effluent from the systems treated.
