Abstract
A process for producing a hydrogenation product of ring-opening polymer by hydrogenating, in the presence of a hydrogenation catalyst, the non-aromatic carbon-to-carbon double bond present in a ring-opening polymer obtained by subjecting to ring-opening polymerization at least one norbornene derivative represented by general formula (I): ##STR1## wherein A and B independently represent hydrogen atoms or hydrocarbon groups having 1-10 carbon atoms, X and Y independently represent hydrogen atoms, halogen atoms or monovalent organic groups, and m is 0 or 1, alone or in combination with a monomer copolymerizable with said norbronene derivative, characterized by using, as the hydrogenation catalyst, a ruthenium compound represented by general formula (II): EQU RuH.sub.k Q.sub.n T.sub.p Z.sub.q (11) wherein Q represents a halogen atom, T represents at least one atomic group selected from the group consisting of CO, NO and CH.sub.3 COCH.sub.2 COCH.sub.3, Z represents PR.sup.1 R.sup.2 R.sup.3 (R.sup.1, R.sub.2 and R.sup.3 independently represent alkyl groups, alkenyl groups or phenyl groups), k is 1 or 2, n is 0, 1 or 2, p is 1 or 2, and q is 2 or 3. This process enables hydrogenation with…
