HIGH-PURITY TUNGSTEN CHLORIDE CATALYST FOR HIGH-YIELD OLEFIN METATHESIS REACTION, AND METHOD FOR PRODUCING NORBORNENE-BASED RING-OPENED POLYMER

摘要

PROBLEM TO BE SOLVED: To provide a high-activity tungsten chloride catalyst that enables a high-yield olefin metathesis reaction used in the production of e.g. a thermoplastic resin composed of a ring-opened polymer of norbornene-based compound monomers, and a method for producing a norbornene-based ring-opened polymer at high yield.;SOLUTION: An olefin metathesis reaction catalyst essentially consists of WC l_x (x=4, 5, or 6) with a purity of 99.99 wt.%(4N) or more and a catalyst compound purity of 95 wt.% or more.;SELECTED DRAWING: None;COPYRIGHT: (C)2019,JPO&INPIT
