［評価方法］
〈曲げ弾性率〉
成形により得られた厚み１／８インチ×幅１／２インチ×長さ５．０インチのバーについて、ＡＳＴＭ−Ｄ−７９０法に準拠して下記条件で測定を行った。
試験速度：２ｍｍ／ｍｉｎ
支点間距離：１００ｍｍ
[Evaluation methods]
<Bending elastic modulus>
The obtained thickness 1/8 inch × 1/2 inch wide × length: 5.0 inches bar by molding, was measured under the following conditions in compliance with ASTM-D-790 method.
Test speed: 2 mm / min
Distance between fulcrums: 100mm
〈アイゾット衝撃強度〉
成形により得られた厚み１／８インチ×幅１／２インチ×長さ５．０インチのバーを半分の２．５インチの長さに切削したものについて、ＡＳＴＭ−Ｄ−２５６法に準拠して下記条件で測定を行なった。
ノッチ回転数：４００ｒｐｍ
ノッチ送り速度：１２０ｍｍ／ｍｉｎ
ハンマー容量：６０ｋｇｆ・ｃｍ
<Izod impact strength>
For those cutting thickness 1/8 inch × 1/2 inch wide × obtained by molding a length: 5.0 inch bar half length 2.5 inches, conforming to ASTM-D-256 method The measurement was performed under the following conditions.
Notch rotation speed: 400rpm
Notch feed speed: 120 mm / min
Hammer capacity: 60kgf · cm
〈体積固有抵抗〉
成形により得られた厚み１／８インチ×幅１／２インチ×長さ５．０インチのバーの両端をカットして１０ｃｍに調整し、カットした端面に導電ペーストを塗り、体積固有抵抗測定用サンプルとした。このサンプルについて、ディジタルマルチメータ（横河Ｍ＆Ｃ株式会社製）を用いて抵抗値を測定し、得られた測定値から下記式で計算により体積固有抵抗値を求めた。
体積固有抵抗値＝（測定値／サンプルバーの長さ）× 断面積
<Volume resistivity>
Both ends of the resulting thick 1/8 inch × 1/2 inch wide × length: 5.0 inches bar by molding cut was adjusted to 10 cm, coated with a conductive paste to the end face was cut, volume resistivity measurement A sample was used. About this sample, resistance value was measured using the digital multimeter (made by Yokogawa M & C Co., Ltd.), and the volume specific resistance value was calculated | required by calculation with the following formula from the obtained measured value.
Volume resistivity = (measured value / sample bar length) x cross-sectional area
