摘要： An α-olefin/unconjugated cyclic polyene copolymer (A) which comprises structural units (I) derived from an α-olefin and structural units (II) derived from a cycloolefin containing a vinyl group, has a molecular-weight distribution (Mw/Mn) of 2.7 or lower, and is noncrystalline or has low crystallinity with a quantity of heat of crystal fusion (ΔH) less than 90 kJ/kg. The copolymer is efficiently produced with a specific transition metal catalyst having a ligand having a phenoxyimine skeleton. The copolymer has a narrower molecular-weight distribution than existing copolymers and has a high vinyl group content. Because of this, the copolymer can give a crosslinked object having excellent tensile properties. When the copolymer is used as a plasticizer for a polymer, e.g., a rubber, the resultant composition shows excellent processability and gives a crosslinked object excellent in mechanical strength, rubber elasticity, etc. Converting vinyl group parts contained in the copolymer to polar groups gives polyolefin materials having various functions imparted thereto.
