    Abstract: A cycloolefin copolymer obtained by ring-opening polymerization characterized in that it has a specific structural unit and gives in differential scanning calorimetry a DSC curve which has a single peak and in which the temperature width of the rising part of the peak is 35°C or smaller, and that the copolymer has a glass transition temperature (Tg) of 110°C or higher. The cycloolefin copolymer is excellent in heat resistance and optical properties and is suitable for forming a film or sheet therefrom. It can be stretched even at a relatively low temperature around the Tg without arousing troubles such as turbidity. Also provided are: a film or sheet which comprises the cycloolefin copolymer and is excellent in optical properties and heat resistance and suitable for stretching at a relatively low temperature; a retardation plate excellent in optical properties and heat resistance and having even retardation; and a process for producing the retardation plate.

    Abstract: PROBLEM TO BE SOLVED: To provide a process for production of a cycloolefin polymer hydride by hydrogenation of a polymer or a copolymer of a cycloolefin compound having a plurality of olefinic unsaturated bonds in the molecule by a simple process inhibiting formation of a gel component and substantially free from gel. SOLUTION: The process for production of the ring-opened cycloolefin polymer hydride comprises ring-opening polymerization of a monomer containing a specific cyclic olefin compound having a plurality of unsaturated bonds in the molecule, and starting the hydrogenation reaction of the resultant ring-opening polymer solution by contact with hydrogen at 40°C to less than 120°C in the presence of a ruthenium compound or a specific metal hydride complex. The cycloolefin polymer hydride requires no removal of gel content by an intensive filtration due to very little content of the gel and may be used for the formation of a suitable desired form.
