1. A composition comprising: a polyazole including a first repeating unit comprising a repeating unit represented by one of the following formulas: wherein Ar is selected from among the following groups:an azole second repeating unit having at least one amino group; and a benzoxazine-based monomer, wherein, assuming that m and n represent the relative molar amount of the first repeating unit and the azole second repeating unit, respectively, in the polyazole such that m+n=1, m ranges from 0.1 to 0.9 and n ranges from 0.1 to 0.9:
and wherein the azole second repeating unit comprises a repeating unit represented by wherein, in Formula 2a, R3, R3′, R3″, R3′″, R4, R4′, R4″, R5, R5′, and R5″ 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, wherein R1 and R2 may be linked to form a C4-C20 carbon ring or a C3-C20 hetero ring; and L represents a linker.
