Abstract

PURPOSE:To prevent the decrease in a light transmission loss by forming a core layer of a polycarbonate polymer having a specific repeating unit and setting the refractive index of the core layer higher by 0.01 than the refractive index of a sheath layer. CONSTITUTION:A solvent to be used for condensation polymn. of a polycarbonate oligomer and BPAF by a solvent method is exemplified by, or example, methylene chloride, chlorobenzene, xylene, etc. Termary amine such as triethyl amine or the quaternary salt thereof may be used in order to accelerate the condensation polymn. The glass transition temp. Tg of the polycarbonate polymer which has the repeating unit expressed by formula I and is obtd. in such a manner is usually >=157 deg.C and the refractive index thereof is <=1.57. The polymer which forms the core layer having the refractive index higher by 0.01 than the refractive index of the sheath layer and has excellent transparency is satisfactory as the polymer to constitute the sheath layer.
