| titleOfInvention | Method for Producing Cyclic Olefin-based Copolymer and Cyclic Olefin-based Copolymer |
| abstract | PROBLEM TO BE SOLVED: To provide a method for efficiently producing a cyclic olefin-based copolymer having an aluminum content reduced to 100 ppm or less. SOLUTION: In the presence of an olefin polymerization catalyst containing a transition metal compound (A) and a compound (B), it does not have an α-olefin (X') having 2 to 20 carbon atoms and an aromatic ring. Production of a cyclic olefin-based copolymer comprising a polymerization step of copolymerizing a cyclic olefin (Y') and a cyclic olefin (Z') having an aromatic ring; and a catalyst removing step of removing the catalyst for olefin polymerization; It is a method, and the cyclic olefin-based copolymer obtained by the production method has a structural unit (X) derived from the α-olefin (X') and a structural unit (Y) derived from the cyclic olefin (Y'). , The cyclic olefin (Z')-derived structural unit (Z), the aluminum content of the cyclic olefin-based copolymer is 100 ppm or less, and the transition metal compound (A) is a transition metal compound ( It contains one or more selected from the group consisting of A-1), a transition metal compound (A-2), and a transition metal compound (A-3), and the compound (B) is an organic metal compound (B). One or more selected from the group consisting of B-1), an organic aluminum oxy compound (B-2), and a compound (B-3) that reacts with the above metal compound (A) to form an ion pair. contains.
