Abstract:
1. A hydrogenated ring-opening metathesis polymer comprising structural units [A] and optional structural units [B] and/or [C] in a constitutional molar ratio defined as [A]/([B]+[C]) from 1/99 to 100/0, said units [A] having the general formula [1]: wherein at least one of R 1 to R 4 is an alkoxymethyl ester-bearing functional group having the general formula [2]: wherein the broken line denotes a valence bond, W 1 is a single bond, divalent C 1 -C 10 hydrocarbon, or divalent C 1 -C 10 hydrocarbon in which one hydrogen atom is substituted by —OR 5 , R 5 is hydrogen, straight, branched or cyclic C 1 -C 10 alkyl, straight, branched or cyclic C 2 -C 10 alkoxyalkyl, or straight, branched or cyclic C 1 -C 10 acyl, and R 6 is straight, branched or cyclic C 1 -C 20 alkyl, and the remainders of R 1 to R 4 are each independently selected from the group consisting of hydrogen, straight, branched or cyclic C 1 -C 20 alkyl, halogen, straight, branched or cyclic C 1 -C 20 haloalkyl, straight, branched or cyclic C 1 -C 20 alkoxy, straight, branched or cyclic C 2 -C 20 alkoxyalkyl, straight, branched or cyclic C 2 -C 20 alkylcarbonyloxy, C 7 -C 20 arylcarbonyloxy, straight, branched or cyclic C 1 -C 20 alkylsulfonyloxy, C 6 -C 20 arylsulfonyloxy, straight, branched or cyclic C 2 -C 20 alkoxycarbonyl, and straight, branched or cyclic C 3 -C 20 alkoxycarbonylalkyl, X 1 which may be the same or different is —O— or —CR 7 2 — wherein R 7 is hydrogen or straight or branched C 1 -C 10 alkyl, and j is 0 or an integer of 1 to 3, said units [B] having the general formula [3]: wherein R 8 to R 11 are each independently hydrogen or straight, branched or cyclic C 1 -C 10 alkyl, X 2 which may be the same or different is —O— or —CR 12 2 — wherein R 12 is hydrogen or straight or branched C 1 -C 10 alkyl, and m is 0 or an integer of 1 to 3, said units [C] having the general formula [4]: wherein R 13 to R 16 are each independently hydrogen or straight, branched or cyclic C 1 -C 10 alkyl, X 3 which may be the same or different is —O— or —CR 17 2 — wherein R 17 is hydrogen or straight or branched C 1 -C 10 alkyl, one of Y 1 and Y 2 is —(C═O)— and the other is —CR 18 2 — wherein R 18 is hydrogen or straight or branched C 1 -C 10 alkyl, and n is 0 or an integer of 1 to 3.
