The miscibility of ethyl cellulose (EC)/copolyamide6/66/1010 (PA-130) in formic acid is studied by viscometry and refractive index techniques at 25A degrees C. Using viscosity data, the criteria Delta b, Delta b';, Delta[eta](m), interaction parameter mu, beta and thermodynamic parameter alpha are calculated. These investigations indicate that blend of EC/PA-130 is miscible when the ethyl cellulose content is more than 50 wt % in the blend. Further the result was also confirmed by refractive index measurements.
