ABSTRACT OF THE DISCLOSURE This invention is directed to a process for the continuous polymerization in a reactor having a narrow cross-section of a water-miscible monomer in an aqueous phase containing at least 20 weight percent monomer. The monomer is polymerized in the presence of an organic liquid employed as a lubricant in a reactor having surfaces which are wetted by the organic liquid but are not wetted by the aqueous phase, the water- soluble polymer so formed being maintained separate from the internal surfaces of the reactor by the organic liquid. Polymers produced by this process are employed, for example, as additives in the manufacture of paper products, agents for the treatment of sewage and industrial waste waters, thickeners and dispersing agents.
