[0103] Examples and comparative examples are given below to further describe the present invention in detail. In addition, the present invention is not limited to these examples. In addition, the measurement evaluation in the Example and the comparative example was performed according to the method shown below.
[0104]
[0105] Using an Ubbelohde viscometer, the viscosity of the dichloromethane solution at 20°C was measured to determine the intrinsic viscosity [η], and the viscosity average molecular weight (Mv) was calculated from the following formula.
[0106] [η]=1.23×10 -5 Mv 0.83
[0107]
[0108] Using liquid chromatography (manufactured by AGILENT TECHNOLOGY, product name: "AGILENT1200"), using "L-columnODS" (manufactured by General Foundation Chemical Substance Evaluation Research Institute, 4.6mmID x 150mm, particle size 3μm) as a column, using acetonitrile / Formic acid buffer=95 / 5 (vol / vol) 3-pentadecylphenol and resorcinol derivatives were measured as a mo...

[0127] (1) Manufacture of polycarbonate oligomers
[0128] In an aqueous sodium hydroxide solution having a concentration of 5.6% by mass, 0.2% by mass of sodium dithionite was added to bisphenol A (BPA) to be dissolved thereafter, and BPA was dissolved therein so that the BPA concentration was 13.5% by mass to prepare a BPA product. Aqueous sodium hydroxide solution. In a tubular reactor with an inner diameter of 6 mm and a tube length of 30 m, the aqueous solution of sodium hydroxide of the above-mentioned BPA was continuously fed at a flow rate of 40 L / hour and dichloromethane was continuously fed at a flow rate of 15 L / hour, while the flow rate of 4.0 kg / hour The flow rate is continuously fed into carbonyl chloride. The tubular reactor has a jacket part, and cooling water is passed through the jacket to keep the temperature of the reaction solution below 40°C.
[0129] The reaction solution sent from the tubular reactor was continuously introduced into a tank reactor wit...
