Polycarbonate copolymer, coating liquid using same, and electrophotographic photosensitive body

A polycarbonate copolymer includes a repeating unit represented by a formula (1) below and a molar copolymer composition represented by Ar2/(Ar1+Ar2) in a range of 25 mol % to 50 mol %. In the formula (1): Ar1 and Ar2 represent a divalent aromatic group; a chain end is terminated by a monovalent aro...

Beschreibung
Zusammenfassung:	A polycarbonate copolymer includes a repeating unit represented by a formula (1) below and a molar copolymer composition represented by Ar2/(Ar1+Ar2) in a range of 25 mol % to 50 mol %. In the formula (1): Ar1 and Ar2 represent a divalent aromatic group; a chain end is terminated by a monovalent aromatic group or a monovalent fluorine-containing aliphatic group; and n represents an average repeating number of an Ar1 block and is a numeral of 1.0 to 3.0, provided that Ar1 and Ar2 are not the same.
