Abstract

Factor analysis by IR and melting-point depression indicated miscibility between poly (vinylidene fluoride/trifluoroethylene) [P (VDF/TrFE)] and poly (methyl methacrylate) (PMMA) in the melt state. χ12 was found to be −0.229 at 160°C. PMMA reduced the rate of crystallization of P (VDF/TrFE) drastically by increasing both ΔG* and ΔGη. The double melting of the blend crystallized nonisothermally originated from the presence of two morphologically different crystals in the paraelectric crystalline state. © 1993 John Wiley & Sons, Inc.
