Abstract
The influence of blend composition on the phase structure and morphology of poly(propylene)/poly(ethylene__‐co‐__octene) blends was studied using SEM. A diameter d~g~ was defined and calculated in real space to discuss the phase structure and morphology of iPP/PEOc blends. The figure‐estimation method was introduced to determine the distribution width of d~g~. It was shown that the distribution of d~g~ obeys a log‐normal distribution and the distribution width σ of d~g~ was calculated. In wave‐number (h) space, the correlation distance, a~c~, was defined by applying light scattering theory to power spectrum images obtained by 2D Fourier transformation. Moreover, a fractal dimension, D~c~, was introduced to describe the uniformity of the spatial distribution.
