Fine particles observed in the emulsion particles of poly (vinylidene fluoride) [PVDF] were morphologically discussed. From the TEM observation of surface replica of the emulsion particles and of the particles dispersed by stirring in liquid N2, it was concluded that the emulsion particles were consisted of fine particles of 20-30nm in diameter. In the fracture surface of PVDF sheets which were melted and then compression-molded, fine particles of 20-30nm in diameter were also observed depending on the annealing conditions.
