Abstract

Disclosed is a polycarbonate having a structure containing a fluorene ring and a structure derived from an isosorbide. This polycarbonate has high heat resistance and a low photoelastic constant, and enables to obtain a film having good transparency. Consequently, this polycarbonate is extremely useful as a polymer for optical use such as a polymer for retardation films.
