Claims preview

1 . A binder for an anode of a secondary battery, comprising: a copolymer comprising, based on a total weight (100 wt %) of repeat units, a) 41 to 54 wt % of first repeat units derived from aliphatic conjugated diene-based first monomers, b) 41 to 54 wt % of second repeat units derived from aromatic vinyl-based second monomers, c) 1.5 to 2.3 wt % of third repeat units derived from unsaturated carboxylic acid-based third monomers, and d) 1 to 10 wt % of fourth repeat units derived from polyethylene glycol mono(meth)acrylate, wherein a weight ratio of the first repeat units to the fourth repeat units (first repeat units/fourth repeat units) is 4.4 to 48.5, and wherein a weight ratio of the second repeat units to the fourth repeat units (second repeat units/fourth repeat units) is 4.4 to 48.5. 2 . The binder for an anode of a secondary battery according to claim 1 , wherein a weight ratio of the third repeat units to the fourth repeat units (third repeat units/fourth repeat units) is 0.01 to 3. 3 . The binder for an anode of a secondary battery according to claim 1 , wherein a weight ratio of the first repeat units to the second repeat units (first repeat units/second repeat units) is 0.73 to 1.38.
