摘要

ABSTRACT OF THE DISCLOSUREA cyclo-olefinic random copolymer composed of analpha-olefin component having 3 to 20 carbon atoms and acyclo-olefin component,(i) said copolymer containing 5 to 99 mole% ofrecurring units derived from said alpha-olefin componenthaving 3 to 20 carbon atoms and 1 to 95 mole% of recurringunits derived from said cyclo-olefin component, and(ii) said copolymer having an intrinsic vis-cosity [?], measured in decalin at 135 °C, of from 0.01 to10 dl/g; andan olefinic random copolymer composed o (A) an olefincomponent having 3 to 20 carbon atoms and (B) a cyclicpolyene component and as required, (C) a cyclo-olefincomponent,(i) said copolymer containing S to 99 mole% ofrecurring units derived from said alpha-olefin component(A) having 3 to 20 carbon atoms and 1 to 95 mole% ofrecurring units derived from said cyclic polyene componentSB) and 0 to 90 mole% of recurring units derived from saidcyclo-olefin component (C), and(ii) said copolymer having an intrinsic vis-cosity [?], measured in decalin at 135 °C, of from 0.01 to10 dl/g; and a process for production thereof. Alsoprovided is a process for producing a cyclo-olefinicrandom copolymer, which comprises copolymerizing an alpha-olefin and a cyclo-olefin in the presence of a catalystformed from(A) a compound of a transition metal of GroupIVB of the periodic table having as a ligand a multi-dentate coordination compound in which at least two con-jugated cycloalkadienyl groups or substituted productsthereof are bonded via a lower alkylene group, and(B) an aluminoxane.
