The morphology of blends of poly(vinylidene fluoride) (PVF 2 ) fractions with poly(methyl acrylate) (PMA), studied by means of polarized light microscopy, exhibits a gradual change in morphology from spherulitic → dendritic → spherulitic both for increasing PMA concentration in the blend and for increasing crystallization temperature. Possible reasons for this change in morphology, viz. the ratio of diffusion constant and growth rate, are discussed. The influence of head to head (H‐H) defects of PVF 2 on the morphology of the blends is discussed on the basis of the polymer‐polymer interaction parameter.
