Experiment example: Melt condensation polymerization process Characterization In Agilent 1200 series number prepared by the melt condensation polymerization process using said in the embodiment and comparison using GPC weight average molecular weights in the stencil [...] PC (Standard) were measured. In addition, in each prepared by the number 1 parts by weight of said in the embodiment and comparison [...], tris (2, 4 - di - tert - butyl phenyl) phosphite 0. 050 parts by weight, octadecaborane it will be burnt - 3 - (3, 5 - di - tert - butyl - 4 - hydroxyphenyl) propionate 0. 010 parts by weight, [...] 0. 030 parts by weight of a, vent attached using Φ 30mm this axial extruder, after pellet grudge, JSW [...] provided 20C (main) injection using a cylinder temperature 300 °C arranges, mold temperature 80 °C the specimen number was stainless steel high pressure liquid coolant. The center of the measuring method of the following properties have said, 1 have shown the result of the following table. 1) chemical resistance: ASTM D638 (sample thickness: 3. 2 mm) based on tensile stress (tensile strength, kg/cm2 ) Measuring (TS0 ) Up. And, after a predetermined table to a solvent such as 1, based on ASTM D543 JIG Strain R1 (PRACTICE B). 0 was based on the database. Each specimen have proved (23 °C) in the cloth made of (2 cm × 2 cm) to such an extent are composed of a central sample solvent volatilizes solvent has been dropped into the contacting a specimen to 168 hours daily cloth. After completing the experiment sample is on a stand-alone fabric and clean solvent completely number, again based on ASTM D638 tensile stress by measuring (TS), TS/TS0 For the bill. 2) room temperature impact strength: ASTM D256 (1/8 inch, Notched Izod) in 23 °C based on measured. 3) low temperature impact strength: ASTM D256 (1/8 inch, Notched Izod) in -30 °C based on measured. 4) flowable (MI): ASTM D1238 (300 °C, 1. 2 kg conditions) were measured based on. As shown in said table 1, the present invention according to comparison example 1 to 3 (in the embodiment 1 and 2) is [...] compared to when the excellent chemical resistance, in particular ethyl acetate and toluene was added to the remarkable difference when used. In addition, low temperature impact strength and cold-impact strength comparison embodiment also compared transmission option.
