    • The process of producing a ring-opening metathesis polymer of the present invention is mainly characterized in that a treatment to decrease the amount of oxygen and/or peroxide in at least one kind of polymerization starting material is performed prior to the ring-opening metathesis polymerization reaction of a cyclic olefin performed in the presence of a ruthenium carbene complex (catalyst). As used herein, the “polymerization starting material” refers to various materials used for a ring-opening metathesis polymerization reaction and present in the reaction system, such as ruthenium carbene complex (catalyst) and cyclic olefin (monomer), as well as solvents, chain transfer agents and the like. In addition, the method for a treatment to decrease the amount of oxygen and/or peroxide include a method comprising applying an adsorbent to a polymerization starting material to remove oxygen and/or peroxide by adsorption, a method comprising applying an antioxidant to a polymerization starting material to decompose oxygen or peroxide and the like.According to the present invention, a ring-opening metathesis polymer can be produced at a higher reaction rate without degrading the high activity inherently possessed by a ruthenium carbene complex (catalyst). Because of being free of a decrease in the concentration of the catalyst maintaining the high activity during reaction, the thus-obtained polymer shows a small difference between polymerization lots and becomes homogeneous, and a polymer having a comparatively sharp molecular weight distribution can be produced.
    • 本发明的开环易位聚合物的制造方法的主要特征在于,在开环易位聚合之前进行至少一种聚合原料中的氧和/或过氧化物的量的减少处理 在钌卡宾络合物(催化剂)的存在下进行的环状烯烃的反应。 如本文所用,“聚合原料”是指用于开环易位聚合反应并存在于反应体系中的各种材料,例如钌卡宾络合物(催化剂)和环烯烃(单体),以及溶剂, 链转移剂等。 此外,减少氧和/或过氧化物的量的处理方法包括将吸附剂施加到聚合起始材料以通过吸附除去氧和/或过氧化物的方法,包括将抗氧化剂施加到聚合开始的方法 用于分解氧气或过氧化物等的物质。 根据本发明,可以以更高的反应速率制备开环易位聚合物,而不会降低钌卡宾配合物(催化剂)固有的高活性。 由于在反应过程中催化剂的浓度降低而保持高的活性,所以由此获得的聚合物在聚合批间之间显示出很小的差异并且变得均匀,并且可以生产具有相当尖锐的分子量分布的聚合物。
