The miscibility and crystallization behavior of the blends of poly(vinylidene fluoride) (PVDF) and ethylene/vinyl acetate(20/80) copolymer (EVAc80) have been studied using a differential scanning calorimeter and a polarizing microscope equipped with a heating stage. From the melting point depression, the values of interaction energy density B were calculated to be $-1.3004;(cal/cm^3)$ and the Flory-Huggins interaction parameter $X_{12}$ was found to be -0.0818 at 445.6K. With increasing concentration of EVAc80, the radial growth rate of spherulite was reduced drastically. The FT-IR analysis of samples quenched from the melt to various temperatures showed increasing content of ${eta}$-phase with increasing amount of blended EVA80 along with lower quenching temperature.
