ISOPRENE-BASED POLYMER CYCLIZED PRODUCT, ALICYCLIC POLYMER, AND OPTICAL RESIN

摘要

An isoprene-based polymer cyclized product obtained by cyclization of an isoprene-based polymer containing structural units expressed by the general formula (1) and having a ratio of content of the structural units to all repeating structural units of 60 mol % or more; an alicyclic polymer obtained by hydrogenation of 50% or more of the carbon-carbon double bonds of the isoprene-based polymer; and an optical resin comprising the isoprene-based polymer cyclized product and alicyclic polymer. (in the general formula (1), R1 indicates a C1 to C10 alkyl group).
