摘要： To provide an aqueous dispersion of a vinylidene fluoride (VdF) copolymer which can be prepared by emulsion-polymerizing VdF monomer with a reactive emulsifying agent and is excellent in stability against sedimentation because an average particle size of the copolymer is as small as not more than 200 nm and a solid content is as high as from 30 to 60 % by weight; an aqueous dispersion of a VdF seed polymer which can be prepared by seed-polymerizing an ethylenically unsaturated monomer in the presence of particles obtained by emulsion-polymerizing VdF monomer with a reactive emulsifying agent and is excellent in stability against sedimentation because an average particle size of the seed polymer is as small as not more than 250 nm and a solid content is as high as from 30 to 60 % by weight; and processes for preparation thereof.
