下記表2に示す割合で各成分を配合し、硬化性樹脂組成物(2)を得た。得られた硬化性樹脂組成物(2)について、下記要領で硬化物における高温条件下での弾性率を測定した。結果を表2に示す。
プレス機を用いて硬化性樹脂組成物(2)を型枠へ流し込み175℃の温度で10分間成型した。型枠から成型物を取り出し、175℃の温度で5時間硬化させた。硬化後の成形物を5mm×54mm×2.4mmのサイズに切り出し、これを試験片とした。
粘弾性測定装置(レオメトリック社製「固体粘弾性測定装置RSAII」)を用い、レクタンギュラーテンション法、周波数1Hz、昇温温度3℃/分の条件で、試験片の260℃における貯蔵弾性率を測定した。
