[0094] The following examples and comparative examples are given to describe the present invention more specifically, but the present invention is not limited to these examples. In addition, the measuring method of a physical property is as follows.
[0095] (1) Tensile physical properties (tensile strength, tensile elongation):
[0096] According to ASTM D638, the tensile strength and tensile elongation (tensile elongation at break) of the resin composition were measured under conditions of a measurement temperature of 23° C., a punctuation distance of 50 mm, and a crosshead speed of 5 mm / min.
[0097] (2) Bending physical properties (bending elastic modulus, bending strength)
[0098] According to ASTM D790, the flexural elastic modulus and flexural strength of the resin composition were measured under conditions of a measurement temperature of 23° C., a support pitch of 80 mm, and a crosshead speed of 3.5 mm / min.
[0099] (3) Izod impact strength:

Synthetic example 1
[0110] 720kgN-methyl-2-pyrrolidone (NMP) is charged into the polymerization tank, containing 46.21% by weight of sodium sulfide (Na 2 S) 420kg of sodium sulfide pentahydrate, after replacing with nitrogen, slowly warming up to 200°C while stirring, distilling out 160kg of water. At this point, 62 moles of H 2 S is volatilized at the same time.
[0111] After the above dehydration process, add 364kg of p-dichlorobenzene and 250kg of NMP into the polymerization tank, and react at 220° C. for 4.5 hours while stirring. Thereafter, while continuing to stir, 59 kg of water was injected, the temperature was raised to 255° C., and the reaction was carried out for 5 hours. After the reaction was completed and cooled to near room temperature, the contents were passed through a 100-mesh sieve to sieve out the granular polymer, washed with acetone twice, and washed with water three times to obtain a washed polymer. The washed polymer was washed with a 3% aqueous ammonium chloride solut...

[0114] The components shown in Table 1 were uniformly dry-blended using a Henschel mixer, supplied to a 46mm bidirectional kneading extruder (PCM-46 manufactured by Ikegai Iron Works Co., Ltd.), and kneaded at a cylinder temperature of 260 to 385°C , made into particles. The thus-obtained pellets were dried at 180°C for 6 hours, and tensile and bending specimens were prepared by using an injection molding machine (IS-75 manufactured by Toshiba Machine Co., Ltd.) at a mold temperature of 180°C and a cylinder temperature of 300 to 380°C. The composition and results of each resin composition are shown in Table 1.
