| titleOfInvention | Method for producing polyarylate resin and method for producing photoreceptor |
| abstract | The invention provides a method for producing polyarylate resin and a method for producing a photoreceptor (especially an electrophotographic photoreceptor). The method for producing a polyarylate resin comprises a synthesis step and a cleaning step. In the synthesis step, the bisphenol derivative and the aromatic dicarboxylic acid derivative are subjected to interfacial polymerization using a polymerization catalyst. In the washing step, the organic phase is washed several times with washing water to obtain a polyarylate resin. The polymerization catalyst is a quaternary ammonium salt represented by the general formula (1). The absorbance of the polyarylate resin is 0.100 or less. The absorbance was measured by filling a 9.1 mass% tetrahydrofuran solution of polyarylate resin in an element having an optical path length of 1.00cm with light having a wavelength of 390 nm. In the general formula (1), X ‑ Represents a halide ion, a hydroxide ion or a bisulfate ion. Y represents propyl, butyl or benzyl. [ CHEM 1 ] |
