A method of producing an emulsion polymer which comprises adding a polymerizable monomer to an emulsion polymer containing a high-molecular-weight compound having a weight average molecular weight of 20,000 to 2,000,000 as a seed polymer, the amount of the unsaturated monomer being 1.5 to 9.5 times the total volume of the solids in the emulsion polymer, and thereafter, polymerizing the monomer in the presence of a film-forming aid.

Method of producing emulsion polymer

An ordinary temperature-curable resin composition comprising (A) a hydrolyzable silyl group-containing fluoroolefin copolymer obtained by polymerizing a monomeric mixture comprising a fluoroolefin as an essential component in the presence of a hydrolyzable silyl group-containing compound, (B) a curing catalyst, and (C) an organic solvent.

Resin composition

A room temperature-curable resin composition consisting essentially of (A) a vinyl polymer containing a basic nitrogen atom and (B) a compound containing both an epoxy group and a hydrolyzable silyl group in each molecule. The composition is especially useful as a paint, an adhesive, or a sealing agent.
