Abstract

Poly(neopentyl glycol adipate), PDPA, is immiscible with poly(vinyl fluoride) but miscible with poly(vinylidene fluoride), indicating the importance of CO ⋯ F-C interaction in achieving miscibility of the blend. Based on the melting point depression of poly(vinylidene fluoride) in the blend, the interaction parameter B was found to be −1.9 cal/cm 3. PDPA is immiscible with poly(vinyl bromide) and with poly( p-bromostyrene). The miscibility of PDPA/poly(vinylidene bromide) blend could not be ascertained because of the poor thermal stability of poly(vinylidene bromide).
