Abstract: PROBLEM TO BE SOLVED: To provide: an optical film having high birefringence, that is, a large phase-difference in a surface direction of a film and in a depth direction thereof, the optical film being useful as a retardation film; an optical member having the optical film; and a method of manufacturing the optical film.
SOLUTION: The optical film is the random copolymer with the chain olefin and norbornenes as the polymerization components. At the diad part and the triad part where the units of the norbornenes are connected, the solid regularity of the diad part is controlled and the copolymer is constituted by the copolymer containing the triad part at a specific rate. In the solid arrangement of the diad part of the copolymer, the rate of the meso type to the racemo type (former/latter in mole ratio) is 0.5 to 20, and the triad part may be contained by 1 to 30 mole% to the unit of whole norbornenes in the copolymer.

Abstract: PROBLEM TO BE SOLVED: To manufacture an organic compound in a high yield by addition or substitution reaction under a mild condition even in reaction using no solvent or reaction in a non-polar solvent. SOLUTION: The catalyst is constituted of a cyclic imide type compound which has an N-substituted cyclic imide skeleton represented by formula (1) (wherein X is an oxygen atom or a hydroxyl group) and of which the solubility parameter due to a Fedors method is 26 [(MPa) ] or less. The catalyst may be constituted of a combination of the cyclic imide type compound and a metal compound. A compound (A) capable of forming radicals and a radical capturing compound (B) are reacted in the presence of this catalyst to form an addition or substitution reaction product of the compounds (A) and (B) or a derivative thereof.
