ABSTRACT:
Cycloolefin/alpha-olefin copolymers in a molar ratio from 5/95 to 95/5, optionally including long linear alpha-olefin, branched alpha-olefins and/or polyenes as additional comonomers, are prepared using a cyclopentadienyl metallocene catalyst system based on a transition metal compound from Group 4 of the Periodic Table of Elements. The copolymers have a high molecular weight, a narrow molecular weight distribution and a substantially uniform, random comonomer distribution.
