发明名称 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 the following formula (A)wherein R1 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 the following formula (B)wherein R2 is a hydrogen atom or a saturated aliphatic hydrocarbon group of 1-16 carbon atoms, and(2) have a reduced viscosity etasp/c which is in the range of 0.1-10 dl/g as measured in a 0.5 g/dl toluene solution at 30° C., hydrogenated copolymers thereof and a process for their production.
