Abstract Binary blends of semicrystalline poly(ethylene oxide) (PEO) with amorphous poly(methylmethacrylate) (PMMA) were investigated during isothermal crystallization (without and with application of electric field) with respect to the segregation behaviour of the spherulitical structure. Microscopic investigations of the blends crystallized without electric field, confirmed earlier results that below 50 wt% PMMA the amorphous domains are distributed in the crystalline phase. The electrocrystallization of the blends in the presence of a strong electric field caused an important increase in nucleating density and formed PEO spherulites with near circular shape, as explained using the bursting theory of Garton and Krasucki.
