PCT No. PCT/JP96/02675 Sec. 371 Date Mar. 19, 1998 Sec. 102(e) Date Mar. 19, 1998 PCT Filed Sep. 18, 1996 PCT Pub. No. WO97/11107 PCT Pub. Date Mar. 27, 1997A polycarbonate exhibiting excellent fluidity and moisture resistance and a process for efficiently producing the polycarbonate are provided. The polycarbonate has a main chain comprising a repeating unit represented by general formula (I): wherein R1 and R2 each represents hydrogen atom or an alkyl group having 1 to 7 carbon atoms; contains 100 ppm by weight or less of a unit of a phenyl salicylate structure expressed by formula (II): in the main chain; and has a viscosity-average molecular weight of 10,000 or more. The polycarbonate is produced in accordance with a process comprising transesterification in the presence of a catalyst comprising a combination of an organic basic compound containing nitrogen and a quaternary phosphonium salt. |
