ALPHA-OLEFIN-CYCLOOLEFIN COPOLYMERS AND PROCESS FOR THEIR PRODUCTION

摘要

alpha -olefin-cycloolefin copolymers which (1) consist essentially of 0-31 % by mole of an alpha -olefin component represented by formula (A) wherein R<1> is a hydrogen atom or a saturated aliphatic hydrocarbon group of 1-16 carbon atoms, and 61-100 % by mole of a cycloolefin component represented by formula (B) wherein R<2> is a hydrogen atom or a saturated aliphatic hydrocarbon group of 1-16 carbon atoms, and (2) have a reduced viscosity eta sp/c which is in the range of 0.1-10 dl/g as measured in a 0.5 g/dl toluene solution at 30 DEG C, hydrogenated copolymers thereof and a process for their production.
