(57) [Summary] [Constitution] 10 to 80% by weight of an aliphatic conjugated diene monomer, 0.5 to 10% by weight of an ethylenically unsaturated carboxylic acid monomer, and 10 other copolymerizable monomers An adhesive composition comprising a copolymer latex that is emulsion-polymerized in the presence of ８９89.5% by weight in the presence of a cyclic unsaturated hydrocarbon having one unsaturated bond in the ring. [Effect] The generation of fine coagulated material is suppressed, and a copolymer latex having good polymerization stability can be efficiently obtained. Further, the paper coating composition comprising the obtained copolymer latex and pigment has excellent adhesive strength, blister resistance, and odor. Furthermore, each of the adhesive compositions such as carpet and rock fiber gives excellent adhesive strength, water resistance and odor. |
