Abstract
A crosslinked copolymer is provided, which includes a copolymer crosslinked by a crosslinking agent. The copolymer is copolymerized of (a) styrene-based monomer, (b) monomer having conjugated double bonds or acrylate ester monomer, and (c) ammonium-containing heterocyclic monomer. The crosslinking agent is (d) or the product of the reaction between and (e) or a combination thereof. Z is wherein each R1 is independently H or C1-4 alkyl group, each R2 is independently H or C1-4 alkyl group, R3 is single bond, —O—, —S—, —CH2—, or —NH—. n is a positive integer. x is 1 to 12, y is 1 to 5, and z is 1 to 5.
