Solvent-induced crystallization and interaction parameter of the blends of bisphenol A polycarbonate and poly(phenyl methacrylate)

Abstract

Blends of bisphenol A polycarbonate (PC) and poly(phenyl methacrylate) (PPMA) were crystallized by tetrahydrofuran (THF) solvent to investigate the phenomena of solvent-induced crystallization. The optimum conditions for solvent induced crystallization in PC have been determined. Interaction parameter has been calculated based on the melting point depression method to estimate the extent of miscibility. A negative interaction parameter (%12 = -0.21) obtained from the melting point depression method suggests that there is some attractive interaction between the blend components.
