Title:
結晶性ノルボルネン系開環重合体水素化物及び成形体
Document Type and Number:
Japanese Patent JP5598326
Kind Code:
B2
Abstract:
A hydrogenated crystalline norbornene ring-opening polymer is obtained by hydrogenating 80% or more of carbon-carbon double bonds of a ring-opening polymer that is obtained by ring-opening polymerization of norbornene monomers including 90 to 100 wt% of 2-norbornene and 0 to 10 wt% of a 2-norbornene derivative having a substituent which does not include an aliphatic carbon-carbon double bond in the presence of a branching agent, the hydrogenated crystalline norbornene ring-opening polymer having a melting point of 110 to 145°C and a branching index of 0.3 to 0.98, and a molded article is obtained by molding the hydrogenated crystalline norbornene ring-opening polymer. The hydrogenated crystalline norbornene ring-opening polymer has excellent industrial productivity, and the molded article has excellent productivity and moisture resistance.
