表1に示す配合処方にしたがって、混練り配合し、各種供試ゴム組成物を得た。これらの配合物を170℃で20分間プレス加硫して加硫物を得て、これらについて以下に示す試験方法によりグリップ性能を評価した。結果を表1に示す。
(株)上島製作所製フラットベルト式摩擦試験機(FR5010型)を用いてグリップ性能を評価した。幅20mm、直径100mmの円筒形のゴム試験片を用い、速度20km/時間、荷重4kgf、路面温度20℃の条件で、路面に対するサンプルのスリップ率を0〜70%まで変化させ、その際に検出される摩擦係数の最大値を読みとった。比較例1の値を100(基準)として指数表示した。指数が大きいほどグリップ性能が高いことを示す。
