Title:
PRODUCTION OF CYCLIC OLEFINIC COPOLYMER
Document Type and Number:
Japanese Patent JP3266368
Kind Code:
B2
Abstract:

PURPOSE: To provide a method for producing a cyclic olefinic copolymer excellent in copolymerizability and polymerization activity, capable of giving the cyclic olefinic copolymer narrow in the mol.wt. distribution and high in the random property at the time of a high-temperature polymerization.
CONSTITUTION: The method for producing a cyclic olefinic copolymer comprises copolymerizing an a-olefin with a cyclic olefin in a non-aromatic solvent in the presence of a catalyst consisting mainly of (A) a transition metal compound of general formula, M1R1aR2bR3cR4d, and (B) a compound capable of forming a cation species from the compound (A) or the derivative of the compound (A) in a non-aromatic solvent.
