Description
また前記リビングアニオン重合によるジエン系ゴムがアルキル−リチウムを開始剤とした芳香族ビニルと共役ジエンとの共重合体であって芳香族ビニルを10〜35重量%及び共役ジエン中のビニル結合量を10〜80重量%含んだ共重合体ゴムである前記ゴム組成物であるのが十分なシリカの分散とゴムの強度を満足し、かつより高い摩擦力を得られるので好ましい。
表Iに示す配合において、加硫系を除くマスターバッチの各成分(重量部)を1.7リットルの実験室バンバリーミキサーで60rpmで5分間混練し、160℃に達したときに放出してマスターバッチを得た。このマスターバッチに加硫系をオープンロールで混練し、シート状未加硫ゴム組成物を得た。このゴムシートを用いて以下に示す試験法で未加硫物性を評価した。結果は表Iに示す。
ムーニー粘度ML1+4(100℃):JIS K−6300に準拠して、ムーニー粘度計にてL型ローター(38.1mm径、厚さ5.5mm)で測定。(予熱1分、測定4分、100℃、2rpm)
引張試験:JIS K−6251に準拠してJIS 3号ダンベルを打ち抜き、500mm/分の引張速度で測定した破断強度を示す。
