摘要：
A polymer binder having softening point of 60° C. to 100° C. including a copolymer formed by polymerizing a first monomer, a second monomer, and a third monomer. The first monomer includes at least one of compounds shown in formula (I) or formula (II). The second monomer includes at least one of compounds shown in formula (III) or formula (IV). The third monomer includes at least one of compounds shown in formula (V):
R11 is selected from an alkyl group having 0 to 3 carbon atoms; n1 is an integer between 2 and 5; R21 is selected from hydrogen or an alkyl group having 1 to 5 carbon atoms, and M is hydrogen or an alkali metal cation; R22 is selected from hydrogen or an alkyl group having 1 to 5 carbon atoms; and R31 is selected from an alkyl group having 1 to 5 carbon atoms.
