The crystal structure and miscibility of PP/EPO biends have been investigated by WAXD, TBA and DSC. The degree of crystallinity of PP/EPO blends decreases with increa-sing content of EPO,and the unit cell parameters are independent of the blend composition. Hosemann's treatment was used to separate crystallite size and distortion broadening. The X-ray diffraction profile was corrected by Cauchy and Gaussian functions. Observations made with TBA and DSC indicated that, though immiscibility of PP/EPO blends, there is a partial interfacial miscibility between the two amorphous phases.

- ethylene-propylene-octene copolymer,
- miscibility
