Cycloolefin copolymer obtained by ring-opening polymerization, use thereof, and process for producing retardation plate comprising the copolymer |
| 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. |
