ABSTRACT:
What is described herein is a precipitation polymerization process and terpolymer products produced thereby. Polymerization is carried out in a reaction mixture of a vinyl lactam, e.g. vinyl pyrrolidone or vinyl caprolactam, a polymerizable carboxylic acid, e.g. acrylic acid or methacrylic acid, and a hydrophobic monomer, e.g. lauryl methacrylate, in a predetermined compositional range, in the presence of a polymerization initiator, and in an aliphatic hydrocarbon solvent, particularly a C.sub.3 -C.sub.10 saturated hydrocarbon, which is branched or unbranched, cyclic or acylic, and, preferably, is heptane or cyclohexane. The terpolymers are obtained in high yield, as a white powder, which can be filtered and dried easily.
