HYDROGENATED NORBORNENE-BASED RING-OPENING POLYMERIZATION POLYMER, RESIN COMPOSITION, AND MOLDED OBJECT |
摘要 |
A hydrogenated norbornene ring-open polymer obtained by hydrogenating 80% or more of main-chain carbon-carbon double bonds of a ring-open polymer obtained by ring-opening polymerization of 2-norbornene. The hydrogenated norbornene ring-open polymer has a weight average molecular weight determined by gel permeation chromatography (GPC) of 50,000 to 200,000, a molecular weight distribution of 1.5 to 10.0, and a melting point of 110 to 145° C. A hydrogenated norbornene ring-open polymer obtained by hydrogenating 80% or more of carbon-carbon double bonds of a ring-open polymer obtained by ring-opening copolymerization of 2-norbornene and a substituent-containing norbornene monomer, wherein the proportion of a repeating unit (A) derived from the 2-norbornene with respect to all repeating units is 90 to 99 wt % and the proportion of a repeating unit (B) derived from the substituent-containing norbornene monomer with respect to all repeating units is 1 to 10 wt %. A resin composition and a molding material. |
