METHOD FOR PRODUCING HYDROGENATED PRODUCT OF CYCLIC OLEFIN-BASED RING-OPENED (CO)POLYMER AND THE RESULTANT HYDROGENATED PRODUCT OF CYCLIC OLEFIN-BASED RING-OPENED (CO)POLYMER

摘要

PROBLEM TO BE SOLVED: To produce in high productivity a cyclic olefin-based ring-opened (co)polymer nearly transparent in hue and suitable for uses including optical applications by hydrogenating a (co)polymer of the corresponding cyclic olefin-based compound having a plurality of olefinic unsaturated bonds in the molecule.;SOLUTION: A method for producing the cyclic olefin-based ring-opened (co)polymer is provided, comprising: the step of starting to bring a solution containing (A) a cyclic olefin-based ring-opened (co)polymer having structural units each derived from a cyclic olefin-based compound represented by general formula(1) and (B) a metal compound into contact with hydrogen under control at 10 to 40°C; and the step of conducting a hydrogenation reaction by raising the temperature of the solution to 100-200°C. In the general formula (1), A¹ and A² are each independently H; halogen atom; 1-10C aliphatic hydrocarbon group; alicyclic hydrocarbon group; aromatic hydrocarbon group; or a polar group selected from alkoxy; OH; ester group; cyano; amido; amino and thiol; or an atom or group selected from the category consisting of halogen atom and/or group substituted with the above polar group(s); wherein A¹ and A² may be the same as or differing from each other; m is an integer of 0 or 1-3; and n is 0 or a positive integer.;COPYRIGHT: (C)2010,JPO&INPIT
