以下では、実施例、参考例および比較例で行った評価の方法について説明する。
実施例、参考例および比較例で得られたマスターバッチペレットから、ミクロトームを用いて、平滑なペレット断面が形成されるように観察用サンプルを切り出した。観察用サンプルのペレット断面について、光学顕微鏡を用いて、反射法により200倍で観察し、写真を撮影した。当該写真撮影を、ペレット断面として1mm2以上の異なる観察範囲で3回行った。
上記3回の写真撮影で得られた各々の写真において、任意に1mm2となる観察範囲を決め、合計3mm2分の観察範囲の中に存在する、金属酸化物(B)の長径5μm以上の凝集粒子の個数を数えた。当該凝集粒子の個数から、ペレット断面1mm2当たりの平均値を算出し、該平均値を金属酸化物(B)の長径5μm以上の凝集粒子の個数とした。
金属酸化物(B)全体における長径5μm以上の凝集粒子の割合については、以下のようにして算出した。
実施例、参考例および比較例で得られたポリアミド樹脂組成物のペレットを、射出成形機(PS-40E:日精樹脂株式会社製)を用いて、ISO 3167に準拠し、多目的試験片A型の成形片を成形した。その際、射出および保圧の時間25秒、冷却時間15秒、金型温度80℃、溶融樹脂温度290℃に設定した。得られた多目的試験片(A型)を用いて、ISO 527に準拠しつつ引張速度5mm/分で引張試験を行い、引張強度を測定した。
上記の多目的試験片(A型)を、熱風循環式オーブン内で、230℃で500時間熱老化させた。23℃で24時間以上冷却した後、ISO 527に準拠しつつ引張速度5mm/分で引張試験を行った。当該引張試験を異なる10本の試験片で行い、その平均値を引張強度とした。また、異なる10本の試験片での引張強度の最大値および最小値も求め、(最大値-最小値)/平均値×100を、引張強度のばらつきとした。
Fe3O4とEBSとを質量比(Fe3O4/EBS)で80/20になるように、ヘンシェルミキサー[FM-20C/I:三井鉱山社製]に投入し、装置を水冷しながら、3,000rpmで10分間攪拌し、Fe3O4とEBSとの混合物1を得た。
