(57) [Summary] [Structure] (a) Aliphatic conjugated diene monomer, (b) Ethylenically unsaturated acid monomer, (c) α-Methylstyrene (d-1) vinylcyano monomer Or (d-2) A method for producing a copolymer latex, comprising emulsion-polymerizing a specific amount of a (meth) acrylic acid ester monomer in an aqueous medium. [Effect] The present invention can easily adjust the gel content, obtains a low-odor latex, has little generation of fine coagulation, and has excellent mechanical stability, and when used as an adhesive, A copolymer latex having improved adhesive strength and blister resistance can be provided. |
