    Abstract: What is described herein is an improved precipitation polymerization process and copolymer products produced thereby. The process herein is carried out by charging a reactor with a solvent in which the copolymer product is substantially insoluble over the entire compositional range of the copolymer, preferably heptane or cyclohexane, and a polymerization initiator, heating to 50° to 150 °C, agitating, and then simultaneously feeding selected amounts of a vinyl lactam and a polymerizable carboxylic acid into said reactor below the surface of the solvent while continuing to agitate the mixture to precipitate the copolymer from solution as a fine, white powder, and recovering the copolymer of defined composition.

    Abstract: A non-aqueous, heterogenous polymerization process comprises heating a reaction mixture of about 5-70%, preferably 10-50%, by weight, of a vinyl amide monomer in an oil as solvent, and a water-soluble cosolvent, and a free radical initiator, optionally in the presence of a crosslinking agent and/or a surfactant, wherein the oil solvent is present in an amount sufficient to keep the resultant polymer in a stirrable state throughout the polymerization. The polymer reaction product is capable of forming a uniform emulsion or gel upon addition of water thereto.
