Description

[technical field] [0001] The present invention relates to a cyclic olefin addition copolymer which has excellent optical transparency, heat resistance and toughness and is suitable for use in optical materials, its composition, and optical materials using the same. [Background technique] [0002] In recent years, with the demand for light weight, small size and high density, optical transparent resins have been used in the field of liquid crystal display element parts such as lenses and other optical parts such as inorganic glass, backlight plates, light guide plates and substrates, which have been used in the past. However, in addition to optical transparency, there is still a need for an improved optically transparent resin material in terms of ripeness resistance, low moisture absorption, adhesiveness, adhesion, and breaking strength. [0003] So far, materials with excellent transparency and heat resistance, such as many proposals for addition polymers of cyclic olefin c...
