Abstract
The polymer buildup problem that may occur in the reactor where the inversion polymerization of vinylchloride is conducted can be effectively ameliorated by way of coating the internal surfaces of the reactor with a mixture comprising an expanding lattice clay, e.g., veegum, and a water-soluble suspending agent, e.g., polyacrylic acid.
