Abstract
There is provided a method for producing an aqueous dispersion of fluorine-containing seed polymer (B) particles, comprising a step for preparing an aqueous dispersion of fluorine-containing polymer (A) particles by polymerizing monomer comprising at least one fluoroolefin in an aqueous dispersion in the presence of a compound (1) represented by the formula: CH═CHCH—O—R, wherein R is a hydrocarbon group which may have an oxygen atom, a nitrogen atom and/or a polar group, and (II) a step for seed-polymerizing ethylenically unsaturated monomer with the fluorine-containing polymer (A) particles in the aqueous dispersion of the fluorine-containing polymer (A) particles. The production method is the method for producing an aqueous dispersion of fluorine-containing seed polymer particles and assures a low foamability and gives an excellent gloss of an obtained coating film and excellent adhesion to a substrate when the fluorine-containing seed polymer particles are used as a coating film forming component of a coating composition.
