Claim 0:
1. A binder composition for a secondary battery electrode, the binder composition comprising a copolymer consisting of the following repeating units:
a) a first repeating unit derived from a conjugated diene-based monomer;
b) second repeating units derived from b1) an aromatic vinyl-based monomer and b2) an unsaturated carboxylic acid-based monomer;
c) a third repeating unit consisting of a crosslinked structure of diacetone acrylamide and adipic acid dihydrazide;
wherein the diacetone acrylamide is included in an amount of 0.1 part by weight to 3 parts by weight with respect to total 100 parts by weight of the conjugated diene-based monomer, the aromatic vinyl-based monomer, and the unsaturated carboxylic acid-based monomer, and
the adipic acid dihydrazide is included in an amount of 0.02 parts by weight to 3 parts by weight with respect to total 100 parts by weight of the conjugated diene-based monomer, the aromatic vinyl-based monomer, and the unsaturated carboxylic acid-based monomer.
