Alicyclic or aromatic polyamides, polyamide films, optical members made by using the same, and polyamide copolymers |
摘要 |
A polyamide having at least an alicyclic or aromatic group exhibiting a light transmittance of 80% or more in the wavelength region of 450 to 700 nm is produced by using an aramide polymer comprising specific structural units at an amount of 50 mol % or more. Colorless transparent alicyclic or aromatic polyamide films having high rigidity and high thermal resistance are provided by using the polyamide. Further, the invention provides various optical members made by using the polyamide or the polyamide films, and polyamide copolymers.
