Claim:
A cyclic olefin addition copolymer comprising a repeating unit (a) shown by the following formula (1) and a repeating unit (b) shown by the following formula (4), and having a number average molecular weight of 10,000 to 1,000,000: wherein A 1 to A 4 individually represent a hydrogen atom, a halogen atom, an alkyl group, alkenyl group, cycloalkyl group, or aryl group having 1-20 carbon atoms, or a reactive silyl group shown by the following formula (2) or (3), provided that at least one of A 1 to A 4 represents the reactive silyl group, X represents —CH 2 — or —O—, and m is either 0 or 1; wherein R 1 , R 2 , and R 3 individually represent a hydrogen atom or a hydrocarbon group having 1-20 carbon atoms, n is an integer from 0 to 5, and Y represents a hydrocarbon residue of an aliphatic diol, an alicyclic diol, or an aromatic diol having 2-20 carbon atoms; wherein R 1 and R 2 individually represent a hydrogen atom or a hydrocarbon group having 1-20 carbon atoms, n is an integer from 0 to 5, and Z represents a hydrocarbon residue of an aliphatic triol, an alicyclic triol, or an aromatic triol having 4-20 carbon atoms; wherein B 1 to B 4 individually represent a hydrogen atom, a substituent selected from a halogen atom, an alkyl group, cycloalkyl group, aryl group, alkenyl group, halogenated hydrocarbon group, alkoxy group, and allyloxy group having 1-20 carbon atoms, or a polar group shown by —(CH 2 ) k Y′ (wherein Y′ represents —C(O)OR 4 or —OC(O)R 5 , R 4 and R 5 represent a substituent selected from an alkyl group, alkenyl group, cycloalkyl group, and aryl group having 1-20 carbon atoms, and halogen substituted groups of these, and k is an integer from 0 to 5), B 1 and B 2 or B 3 and B 4 may form an alkydenyl group, B 1 and B 3 , B 1 and B 4 , B 2 and B 3 , or B 2 and B 4 may form a cycloalkylene group or a cycloalkenylene group, and p is an integer from 0 to 2.
