A copolymer of vinylidene chloride and vinyl chloride containing 13.5% by weight of the latter has been solution blended with four aliphatic polyesters: poly(ϵ‐caprolactone), poly(2,2‐dimethyl‐1,3‐propylene adipate), poly(1,4‐cyclohexanedimethylene succinate), and poly(2,2‐dimethyl‐1,3‐propylene succinate). Each blend was examined visually and by differential scanning calorimetry. All blends with the copolymer form a single miscible amorphous phase at all compositions and all temperatures except for the latter mentioned polyester, which exhibits liquid–liquid phase separation at temperatures above a measured cloud point curve. Information about interactions between the components in each blend is estimated from melting point data and discussed.
