Abstract
The present invention relates to a process for producing heat-treated vinylidene fluoride polymer particles which exhibit excellent dispersibility and solubility in aprotic polar solvents, improved colour and are less prone to agglomeration and to uses of said vinylidene fluoride polymer particles in electrodes or separators in electrochemical devices and in filtration membranes. The process comprises providing an aqueous dispersion of the VDF-based polymer particles, thermally treating it under stirring and isolating the heat-treated polymer particles.
