To provide an addition polymer of norbornene which is excellent in transparency, chemical resistance, and optical properties, has a high glass-transition temperature, a low water absorption, and a low linear expansion coefficient and is soluble in a general solvent, and to provide a molded article comprising it and its use.
This addition polymer of a norbornene compound consists only of a repeating unit of a norbornene compound monomer. Not less than 70 mol% of all the repeating units are the total of (a) repeating units of a norbornene compound monomer which consists of only carbon and hydrogen and in which all the carbon atoms are related with the structure of its condensed ring skeleton and (b) repeating units of a norbornene compound monomer which has a structure in which, a part of hydrogen atoms of a norbornene compound monomer which consists of only carbon and hydrogen and in which all the carbon atoms are related with the structure of its condensed ring skeleton, are substituted with a hydrocarbon group having two or less carbon atoms. The molar ratio of the repeating unit (a)/the repeating unit (b) is in the range of 10/90-98/2.
