Abstract
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.
