摘要： The object of the present disclosure is to provide a method for producing a crosslinked polymer by radical polymerization of a monomer composition, by which method a desired crosslinked polymer can be produced in a high solid content with good productivity (also at a low production cost), and a crosslinked polymer obtained by the production method and a coating composition containing the same.A method for producing a crosslinked polymer having a weight average molecular weight of 15000 to 200000, the method comprising step [I] of obtaining a crosslinked polymer (A) by conducting polymerization of a monomer composition comprising 2 to 30% by weight of a polyfunctional methacrylate having 2 to 4 functional groups (a) and 98 to 70% by weight of one or more polymerizable monomers selected from the group consisting of monofunctional (meth)acrylates, (meth)acrylic acid, and monofunctional vinyl aromatic compounds (b) in an organic solvent in the presence of a radical polymerization initiator in a temperature region where the radical polymerization initiator comes to have a half-life of 4 to 18 minutes.
