Abstract:
1. A hydrogenated ring-opening metathesis polymer which contains at least one of structural unit [B] and structural unit [C] and which optionally contains structural unit [A] with structural unit [A] having the following general formula [1]: wherein at least one of R 1 to R 4 represents a functional group having a tertiary ester group of a cyclic alkyl of the following general formula [2]: wherein the chain line represents a connecting means, R 5 represents a hydrogen atom, a linear, branched or cyclic alkyl group having 1 to 10 carbon atoms, a linear, branched or cyclic alkoxyalkyl group having 2 to 10 carbon atoms, or a linear, branched or cyclic acyl group having 1 to 10 carbon atoms, R 6 represents a linear, branched or cyclic alkyl group having 1 to 10 carbon atoms, W 1 represents a single bond or a (k+2)-valent hydrocarbon group having 1 to 10 carbon atoms, Z represents a divalent hydrocarbon group having 2 to 15 carbon atoms and forms a single ring or a cross-linked ring together with carbon atoms to be bonded, k represents 0 or 1, and the remaining groups of R 1 to R 4 are selected each independently from a hydrogen atom, a linear, branched or cyclic alkyl group having 1 to 20 carbon atoms, halogen atoms, a linear, branched or cyclic halogenated alkyl group having 1 to 20 carbon atoms, a linear, branched or cyclic alkoxy group having 1 to 20 carbon atoms, a linear, branched or cyclic alkoxyalkyl group having 2 to 20 carbon atoms, a linear, branched or cyclic alkylcarbonyloxy group having 2 to 20 carbon atoms, an arylcarbonyloxy group having 6 to 20 carbon atoms, a linear, branched or cyclic alkylsulfonyloxy group having 1 to 20 carbon atoms, an arylsulfonyloxy group having 6 to 20 carbon atoms, a linear, branched or cyclic alkoxycarbonyl group having 2 to 20 carbon atoms, or a linear, branched or cyclic alkoxycarbonylalkyl group having 3 to 20 carbon atoms, and X 1 s are the same or different and represent —O— or —CR 7 2 — wherein R 7 represents a hydrogen atom or a linear or branched alkyl group having 1 to 10 carbon atoms, j represents an integer of 0 or 1 to 3, structural unit [B] having the following general formula [3]:  wherein R structural unit [C] having the following general formula [4]:  wherein R wherein at least one of X wherein the molar ratio of [A]/([B] and [C]) is 0/100 to 99/1 and the ratio of the weight-average molecular weight Mw to the number-average molecular weight Mn (Mw/Mn) is more than 2.0 and less than 5.0.
