A continuous process for the preparation of water-soluble copolymers of vinyl carboxylic acids and lower alkyl acrylates is disclosed. The process employs a tubular reactor and polymerizes the monomers in aqueous solution in the presence of a free radical catalyst. Molecular weights of from 3,000-300,000 and preferably from about 5,000-25,000 are obtained utilizing this process. |
