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.
摘要:
Aqueous dispersion of a fluorine-containing copolymer which is prepared by, in an aqueous dispersion containing fluorine-containing copolymer particles which comprise 70 to 95% by mole of vinylidene fluoride and 5 to 30% by mole of chlorotrifluoroethylene, seed-polymerizing 20 to 100 parts by weight of an acrylic acid ester and/or a methacrylic acid ester in the presence of 100 parts by weight of the fluorine-containing copolymer particles. The aqueous dispersion assures excellent film forming property, and can provide a highly glossy coating excellent in mechanical properties, transparency at clear coating and weatherability.

摘要:
Aqueous dispersion of a vinylidene fluoride (VdF) polymer which comprises a VdF polymer having a particle size of not more than 200 nm and contains 30 to 50% by weight of solids and not more than 1% by weight of a fluorine-containing surfactant on the basis of water. This aqueous dispersion is prepared by emulsion-polymerizing VdF monomer or a monomer mixture containing VdF under coexistence of not more than 1% by weight of the fluorine-containing surfactant and 0.001 to 0.1% by weight of a nonionic non-fluorine-containing surfactant on the basis of water, and is suitably used for paints.
