ABSTRACT:
A copolymer has a polystyrene reduced number average molecular weight of 103-108, and includes repeating units represented by formulas (1), (2), and (3), —Ar1—  (3)The copolymer has an excellent solubility in an organic solvent, and a high glass transition temperature in good valance. Further, a polymer LED has high performance, such as low-voltage driving and high luminance.
