Document Type and Number:
WIPO Patent Application WO/2015/098759
Kind Code:
A1
Abstract:
[Problem] To provide a method for producing an acrylic copolymer, which is capable of reducing the amount of monomers remaining in a polymer that is produced by a suspension polymerization method.
[Solution] A method for producing an acrylic copolymer according to the present invention is a method for producing an acrylic copolymer by suspension polymerization from a reaction system which is composed of a dispersion medium and a dispersed phase that contains a monomer mixture containing an alkyl (meth)acrylate monomer, which serves as a first monomer, and a monomer other than alkyl (meth)acrylate monomers, which serves as a second monomer. The dispersed phase contains a saturated hydrocarbon-based solvent that is a good solvent for the monomer mixture but a poor solvent for the acrylic copolymer.
