Degradation of a Vinylidene Chloride Copolymer in Solution

Article metrics


SOME observations have recently been made on the changes in viscosity of solutions of a copolymer containing approximately 85 per cent vinylidene chloride, 13 per cent vinyl chloride and 2 per cent acrylonitrile (by weight). The polymer was soluble in hot, but not in cold, tetrahydrofuran : once it had been dissolved by heating in the solvent at 60–65° C. for 2–3 min., the solution could be cooled to room temperature without gelling or precipitation.
