    • The present invention provides a method for hydrogenating a metathesis polymer solution obtained by polymerization in the presence of a metathesis polymerization catalyst comprising (a) the catalyst component of a transition metal compound and (b) the co-catalyst component of a metal compound by bringing the above solution into contact with hydrogen, without adding an inactivating agent for the metathesis polymerization catalyst, that is, with the solution left to contain the catalyst, in the presence of a hydrogenation catalyst comprising a transition metal compound (c) and a reductive metal compound (d) and if necessary by adding an acid-binding compound. According to this method, both addition of the inactivating agent and removal of the metathesis polymerization catalyst are not necessary, and also the hydrogenation can be carried out at a lower temperature and under a lower pressure than in hydrogenation with a supported-type catalyst, so that the efficiency of production of the hydrogenated product is excellent. Besides, even if tungsten hexachloride (WCl.sub.6), etc. are used as the catalyst component, an effect of preventing a hydrogenation reactor from corrosion by a hydrogen halide, can be obtained.
    • 本发明提供一种在易位聚合催化剂存在下,通过聚合反应得到的复分解聚合物溶液的氢化方法,所述分解聚合催化剂包含(a)过渡金属化合物的催化剂组分和(b)金属化合物的助催化剂组分, 在含有过渡金属化合物(c)和还原性金属(c)的氢化催化剂的存在下,将上述溶液与氢接触,而不添加用于易位聚合催化剂的灭活剂,即溶液含有催化剂 化合物(d),如果需要,加入酸结合化合物。 根据该方法,不需要添加灭活剂和去除复分解聚合催化剂,并且在与负载型催化剂的氢化相比,在较低的温度和低的压力下氢化可以进行,因此 氢化产物的生产效率优异。 此外,即使使用六氯化钨(WCl 6)等作为催化剂成分,也可以得到防止氢化反应器被卤化氢腐蚀的效果。

    • A resin obtained by subjecting a norbornene type monomer having an aromatic ring structure (e.g. 5-phenyl-2-norbornene) to ring-opening polymerization and hydrogenating 95% or more of the unsaturated bonds in the backbone structure of the resulting polymer by the use of a catalyst composed of a combination of a transition metal compound and an alkyl metal compound, while leaving 80% or more of the aromatic ring structures, which resin has not only a high refractive index but also characteristics of a hydrogenated norbornene ring-opening polymerization product, i.e., excellent heat resistance, transparency, low birefringent properties, weather resistance, light resistance, low water absorption properties, moisture resistance, small dielectric constant, small dielectric loss, chemical resistance, etc., said resin being usable in optical materials, medical tools and materials, tools and materials for treating electronic parts, etc.
