ABSTRACT:
Polyarylene ether for optical communications, expressed by the formula 1: ##STR1## The polyarylene ether has excellent resistance to heat and film processing properties and the light absorption loss in the wavelength range for optical communications is low. Also, by controlling the copolymerization ratio of a monomer whose hydrogen of C--H bond is substituted by F and a monomer whose hydrogen of C--H bond is substituted by Cl, the refractive index of the polymer can be adjusted to a level suitable for an optical material used for optical communications.
