[0207] [Measurement conditions]

[0208] <Polysiloxane and Cyclic Siloxane Content>

[0209] Calculated using NMR. 1 The chemical shift in H-NMR analysis was based on 0 ppm of the peak of TMS (tetramethylsilane).

[0210] pass 1 H-NMR observed peaks from methyl groups on Si of decamethylpentacyclosiloxane (D5) and octamethyltetracyclosiloxane (D4), which are cyclic siloxanes corresponding to polysiloxane, at 0.1-1.0 ppm, 0.079 ppm, and 0.094 ppm, respectively. The sum of the peak areas of 0.079 ppm and 0.094 ppm was taken as the cyclic siloxane content, and the value of the peak areas of 0.079 ppm and 0.094 ppm was subtracted from the peak area of ​​0.1-1.0 ppm as the polysiloxane content, and the polysiloxane generation rate and cyclic siloxane generation rate were calculated based on this value.

[0211] <Polystyrene equivalent weight average molecular weight (Mw, Mn, Mw / Mn)>

[0212] GPC (gel permeation chromatography) was used, chloroform was used as the developing solvent, and a standard polystyrene (Shodex STANDARD, SM-105) with a known molecular weight (molecular weight distribution = 1) was used to prepare a calibration curve. The elution time and molecular weight value of each peak were marked with the measured standard polystyrene, and approximated by a cubic equation to prepare a calibration curve.

[0213] Thereafter, based on the obtained calibration curve, the weight average molecular weight (Mw) was determined as a polystyrene-equivalent value from the following formula.

[0214] [Calculation formula]

[0215] Mw=Σ(Wi×Mi) / Σ(Wi)

[0216] Mn=Σ(Ni×Mi) / Σ(Ni)

[0217] In the above formula, i represents the i-th split point when splitting the molecular weight M, Wi represents the i-th weight, Mi represents the i-th molecular weight, and Ni represents the number of molecules of the i-th. In addition, the molecular weight M represents the molecular weight value converted to polystyrene at the same dissolution time in the normalized curve.

[0218] It should be noted that Mw / Mn represents molecular weight dispersion and is a parameter for determining whether the molecular weight distribution is broad or narrow. A value closer to 1.0 indicates a narrower molecular weight distribution, and a larger value indicates a wider molecular weight distribution.

After the polycarbonate was melted, 10.00 g of the composition prepared in Example 2 was dropped using a dropping funnel. The pressure was gradually reduced at 240°C, and the temperature was raised to 260°C after reaching 2 hPa, and stirred for 1 hour, thereby obtaining a white siloxane block copolymer polycarbonate.

[0273] The Mw and Mn of the siloxane block copolymer polycarbonate were measured by GPC and were found to be Mw 101,401 and Mn 57,702.

[0274] [Example c]

[0275] A polycarbonate copolymer was produced using the composition produced in Example 2 and a polycarbonate compound.

[0276] Specifically, 2.50 g of the composition prepared in Example 2 and 10.00 g of polycarbonate (molecular weight = Mw 18,783, Mn 10,227, cesium carbonate was added as a catalyst, containing 0.167 μmol relative to the molar number of bisphenol A, Tg = 122° C.) were heated to 260° C. under reduced pressure (2 hPa). Stirring was carried out at 260° C. for 1 hour and 20 minutes, thereby obtaining a white powdery siloxane block copolymer polycarbonate.

[0277] The Mw and Mn of the siloxane block copolymer polycarbonate were measured by GPC and were found to be Mw 356,597 and Mn 79,718. The Tg was 140°C.
