    • PURPOSE: A polymer composition is provided to obtain a cross-linked polymer composition with enhanced capability of retaining phosphoric acid at a wide range of temperature and to secure long-term durability and enhanced proton conductivity. CONSTITUTION: A polymer composition comprises: a polymer having a first repeating unit represented by chemical formula 1 and a second repeating unit represented by chemical formula 2, and an oxazine-based monomer. In chemical formula 1, Ar is a substituted or unsubstituted C6-C20 arylene group or a substituted or unsubstituted C3-C20 heteroarylene group and m is a number from 0.01 from 1. In chemical formula 2, R1 is a hydrogen atom, a substituted or unsubstituted C1-C20 alkyl group, a substituted or unsubstituted C1-C20 alkoxy group, a substituted or unsubstituted C6-C20 aryl group, a substituted or unsubstituted C6-C20 aryloxy group, a substituted or unsubstituted C3-C20 heteroaryl group, or a substituted or unsubstituted C3-C20 heteroaryloxy group; R2 and R3 are each independently a hydrogen atom, an unsubstituted or substituted C1-C20 alkyl group, an unsubstituted or substituted C1-C20 alkoxy group, an unsubstituted or substituted C6-C20 aryl group, an unsubstituted or substituted C6-C20 aryloxy group, an unsubstituted or substituted C3-C20 heteroaryl group, or an unsubstituted or substituted C3-C20 heteroaryloxy group, or R2 and R3 may be linked to form a C4-C20 carbocyclic group or a C3-C20 heterocyclic group; and n is a number from 0 to 0.99.
