Embodiment
[0163] Hereinafter, the present embodiment will be described in more detail using examples, but the present embodiment is not limited to these examples.
[0164]
[0165] Use JNM-AL400 manufactured by JEOL Ltd., according to 1 H-NMR and 13 C-NMR (400MHz, the solvent is CDCl 3 ) to calculate the measured value.
[0166]
[0167] A differential scanning calorimetry device DSC6200 manufactured by Seiko Instruments Co., Ltd. was used. Under the condition of flowing nitrogen at 30ml / min., heat up from 30°C to 200°C at 10°C / min., then cool down from 200°C to 30°C at 50°C / min. °C was raised to 200 °C. The intersection point of the baseline and the tangent of the inflection point at the time of the second temperature rise was defined as the glass transition temperature.

[0203] Synthesis Example 1 [Synthesis of polycarbonate resin terminal terminator]
[0204] According to Handbook of Organic Chemistry P143-150, use 4-Hydroxybenzoic acid manufactured by Tokyo Chemical Industry Co., Ltd. and 1-Cetyl Alcohol manufactured by Tokyo Chemical Industry Co., Ltd. to perform esterification by dehydration reaction to obtain hexadecyl p-hydroxybenzoate ester (CEPB).
Synthetic example 2
[0205] Synthesis Example 2 [Manufacture of Polycarbonate-based Resin (A-1) Pellets]
[0206] 7.1 kg (31.14 mol) of bisphenol A (hereinafter referred to as BPA) manufactured by Nippon Steel Sumitomo Chemical Co., Ltd. and 30 g of sodium dithionite were added to 57.2 kg of a 9w / w% sodium hydroxide aqueous solution and dissolved. 40 kg of dichloromethane was added thereto, the temperature of the solution was kept in the range of 15°C to 25°C while stirring, and 4.33 kg of phosgene was blown in over 30 minutes. After blowing into phosgene, add 6kg of 9w / w% aqueous sodium hydroxide solution, 11kg of methylene chloride, and dissolve 443g (1.22mol) of cetyl p-hydroxybenzoate (CEPB) as a terminal terminator in Dichloromethane 10kg obtained solution, stirred vigorously to make it emulsified. And then 10 ml of triethylamine as a polymerization catalyst was added to the solution, and polymerization was performed for about 40 minutes.
[0207] The polymerization liquid is separated into...
