Problems solved by technology

However, this document discloses only polybutylene terephthalate polymerized from macrocyclic butylene terephthalate oligomers as the base polymer for this production method.
In addition, this document also discloses that in the melt kneading of polyethylene terephthalate, macrocyclic butylene terephthalate oligomer, and organic clay, macrocyclic butylene terephthalate Insufficient conversion of glycol ester oligomers to polymers, therefore, cannot be molded into test pieces
That is, there is no indication in this document that this production method can be effectively applied to base resins other than polybutylene terephthalate.

[0234] The following examples illustrate the present invention. But the present invention is not limited thereto. In addition, evaluation is performed by implementing the following items.

[0235] (I) Evaluation items

[0236] (I-1) Surface resistivity

[0237] A square plate with a width of 45 mm x a length of 80 mm x a thickness of 2 mm was molded under two injection conditions of an injection speed of 10 mm / sec and an injection speed of 50 mm / sec. Take out the molded products of the 2nd, 4th, 6th, 8th, and 10th injections after purification, place them in an environment with a temperature of 23°C and a relative humidity of 50% for 24 hours, and then use a digital insulation meter (Toa Denpa Kogyo Co., Ltd. )) and a low resistivity meter (manufactured by Mitsubishi Chemical Corporation) measured the surface resistivity of the five square plates, and calculated the average value.
