Abstract: An aqueous dispersion containing a particulate resin composite that contains a fluorine-containing resin and an inorganic polymer. The fluorine-containing resin contains a hydrolyzable silyl group-containing unsaturated monomer unit.

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: CH2?CHCH2—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.

Abstract: An object of the present invention is to provide a method for producing a fluoropolymer which produces a large number of particles with a small particle size using a specific non-fluorous compound having surfactant ability. The method for producing a fluoropolymer includes aqueous dispersion polymerization of a monomer including at least one fluoroolefin in the presence of a compound represented by the formula: CH2?CHCH2—O—(C?O)CHXCH2COO(CH2)nCH3 (in the formula, X is H or SO3Y wherein Y is NH4 or an alkaline metal; and n is an integer of 0 to 19.

Abstract: The present invention aims to provide a composition that forms a film excellent in freeze-thaw resistance, as well as in transparency, weather resistance, adhesion to a base material, and blocking resistance. The present invention relates to a composition comprising polymer particles (A) and a crosslinking agent (B), the polymer particles (A) obtainable by seed polymerization of at least one monomer selected from the group consisting of acrylic acid esters and methacrylic acid esters, an unsaturated carboxylic acid, and a hydrolyzable silyl group-containing monomer in the presence of fluoropolymer particles as seed particles, and the crosslinking agent (B) having at least one group selected from the group consisting of aziridine, carbodiimide, and oxazoline groups.
