| 发明名称 | Binder for secondary battery electrodes | ||
| 摘要 | A binder for secondary battery electrodes contains a copolymer latex obtained by emulsion polymerization of a monomer composition containing 12.0 to 39.5 wt % of an aliphatic conjugated diene-based monomer, 1.5 to 8.5 wt % of an unsaturated carboxylic acid alkyl ester monomer, 0.1 to 10.0 wt % of an ethylene-based unsaturated carboxylic acid monomer, and 42.0 to 86.4 wt % of a monomer that is copolymerizable therewith, wherein 50 to 100 wt % of the copolymer latex is toluene-insoluble. | ||

| 主权项 | 1. A binder for secondary battery electrodes comprising a copolymer latex obtained by emulsion polymerization of a monomer composition comprising: 12.0 to 39.5 wt % of an aliphatic conjugated diene-based monomer, 1.5 to 8.5 wt % of an unsaturated carboxylic acid alkyl ester monomer, 0.1 to 10.0 wt % of an ethylene-based unsaturated carboxylic acid monomer, and 42.0 to 86.4 wt % of a monomer that is copolymerizable therewith, wherein the ethylene-based unsaturated carboxylic acid monomer contains dicarboxylic acid in amounts of 1 2% by weight based on total amount of the monomers, and wherein 80 to 99 wt % of the copolymer latex is toluene-insoluble and, wherein the copolymer latex further comprises water as a dispersion medium. | ||
