    摘要: Coating compositions based on stable aqueous dispersions of particles of vinylidene fluoride polymer are prepared by bringing into admixture unstabilized particles of vinylidene fluoride polymer, liquid organic active solvent for the vinylidene fluoride polymer, liquid nonsolvent, which may be liquid organic nonsolvent, water or a combination of liquid organic nonsolvent and water, and, if not present in the liquid nonsolvent, water. The mixing is conducted such that the particles of vinylidene fluoride polymer are wetted by the dispersion vehicle, yet the particles are not substantially solubilized by the active solvent.
