<p>PURPOSE: A polysufone-based polymer is provided to obtain a polymer electrolyte membrane with high hydrogen ion conductivity, low methanol permeability, and excellent moisture content. CONSTITUTION: A polysufone-based polymer comprises a repeating unit represented by chemical formula 1. In chemical formula 1, X is a single bond or Ar1; R1, R2, R3, R4, R5 and R6 are hydrogen, -SO3M, -SO3M substituent-(non)containing C1~50 alkyl group, C2~50 alkenyl group, C2~50 alkynyl group, C5~50 cycloalkyl group, C6~50 aryl group, C2~50 heteroaryl group, C7~50 alkylaryl group, or C1~50 alkoxy group; M is hydrogen, lithium, sodium or potassium; a, b, c, and d are an integer of 0-5; e and f are an integer of 0-2; and n is 2-10,000 as the degree of polymerization.</p> |
