α--olefin-cyclic olefin copolymer and a method of manufacturing the same, molded body including a α- olefin-cyclic olefin copolymer

摘要

PROBLEM TO BE SOLVED: To provide an olefin copolymer having high refraction index and low Abbe's number and a process for producing the same, and an optical component including the copolymer.;SOLUTION: An α-olefin/cyclic olefin copolymer includes a 2-30C α-olefin unit and a cyclic olefin unit represented by the general formula (I), wherein x is an integer of 0 or 1 or more, R⁸¹-R⁸⁸ is selected from a hydrogen atom, an aliphatic hydrocarbon, and an aromatic hydrocarbon, R⁹¹-R⁹⁴ is selected from a hydrogen atom, an aliphatic hydrocarbon, and an aromatic hydrocarbon, wherein two adjacent groups together may form a monocyclic or a polycyclic aromatic ring.;COPYRIGHT: (C)2011,JPO&INPIT
