Latest Patents
Yoshimi Suwa holds a patent for a "Cycloolefin copolymer obtained by ring-opening polymerization, use thereof, and process for producing retardation plate comprising the copolymer." This invention is characterized by a specific structural unit and exhibits a single peak in a derivative differential scanning calorimetry curve obtained by differential scanning calorimeter (DSC). The copolymer has a temperature width of the rising part in the peak of 35°C or below and a glass transition temperature (Tg) of 110°C or above. The cycloolefin copolymer demonstrates excellent heat resistance and optical properties, making it suitable for the formation of films or sheets. It can be stretched at relatively low temperatures around the Tg without causing issues such as cloudiness. Additionally, the invention includes a retardation plate with uniform retardation and excellent optical properties.
