Claim:
A photo-reactive norbornene-based copolymer, including repeating units derived from the following compounds of Chemical Formulae 1 and 2 as monomers: in Chemical Formulae 1 and 2, q and q′ are integers of 0 to 4, at least one of R1, R2, R3, and R4 is a radical selected from the group consisting of the compounds represented by the following Chemical Formulae 1a and 1b, at least one of R1′, R2′, R3′, and R4′ is a radical represented by the following Chemical Formula 2a, R1 to R4, and R1′ to R4′ except the radicals of Chemical Formulae 1a, 1b, and 2a are same or different each other, and independently selected from the group consisting of hydrogen; a halogen; a substituted or unsubstituted C 1 -C 20 linear or branched alkyl; a substituted or unsubstituted C 2 -C 20 linear or branched alkenyl; a substituted or unsubstituted C 2 -C 20 linear or branched alkynyl; a substituted or unsubstituted C 3 -C 12 cycloalkyl; a substituted or unsubstituted C 6 -C 40 aryl; and a polar group including at least one selected from oxygen, nitrogen, phosphorus, sulfur, silicon, and boron, and when R1 to R4, and R1′ to R4′ are not hydrogen; halogen; or polar group, at least one combination selected from the group consisting of R1 and R2, R1′ and R2′, R3 and R4, and R3′ and R4′ may be connected each other so as to form a C 1 -C 10 alkylidene group; or R1 or R2 may be connected to any one of R3 and R4, or R1′ or R2′ may be connected to any one of R3′ and R4′ so as to form a C 4 -C 12 saturated or unsaturated aliphatic ring or a C 6 -C 24 aromatic ring: in Chemical Formulae 1a, 1b, and 2a, A is a chemical bond, oxygen, sulfur, or —NH—, B is selected from the group consisting of a chemical bond, a substituted or unsubstituted C 1 -C 20 alkylene, a carbonyl group, a carboxyl group, an ester, a substituted or unsubstituted C 6 -C 40 arylene, and a substituted or unsubstituted C 6 -C 40 hetero arylene, X is oxygen or sulfur, R9 is selected from the group consisting of a chemical bond, a substituted or unsubstituted C 1 -C 20 alkylene, a substituted or unsubstituted C 2 -C 20 alkenylene, a substituted or unsubstituted C 3 -C 12 cycloalkylene; a substituted or unsubstituted C 6 -C 40 arylene; a substituted or unsubstituted C 7 -C 15 aralkylene, and a substituted or unsubstituted C 2 -C 20 alkynylene, Ra is hydrogen or methoxy, at least one of R10, R11, R12, R13, and R14 is a halogen or a halogen-substituted C 1 -C 20 alkyl, and the rest of R10 to R14, and R10′ to R13′ are same or different each other, and independently selected from the group consisting of hydrogen, a substituted or unsubstituted C 1 -C 20 alkyl; a substituted or unsubstituted C 1 -C 20 alkoxy; a substituted or unsubstituted C 6 -C 30 aryloxy; a substituted or unsubstituted C 6 -C 40 aryl; a C 6 -C 40 hetero aryl including a hetero atom of Group 14, 15, or 16; and a substituted or unsubstituted C 6 -C 40 alkoxyaryl, with the proviso that the rest of R10 to R14 in the Chemical Formula 1b are not hydrogen.
