MANUFACTURING METHOD OF HIGH-PURITY HYDROGENATED-RING OPENING POLYMERIZATION POLYMER AND HIGH-PURITY HYDROGENATED-RING OPENING POLYMERIZATION POLYMER MANUFACTURED THEREFROM

摘要

In the present invention, disclosed is a method for improving transparency of a final polymer by conducting a catalyst residue removal step which adds montmorillonite in a polymer solution to be processed, and effectively removing a catalyst residue in a polymer, wherein the polymer solution is obtained by hydrogenating a tetracyclododecene derivative and a ring opening polymer of dicyclopentadiene by using a hydrogenation catalyst comprising a nickel-based catalyst.;COPYRIGHT KIPO 2014
