Description
前記高分子量重合体成分(A)の芳香族ビニル化合物の結合量(S1)(質量%)及び共役ジエン化合物部分のビニル結合量(V1)(%)と、前記低分子量重合体成分(B)の芳香族ビニル化合物の結合量(S2)(質量%)及び共役ジエン化合物部分のビニル結合量(V2)(%)とが、下記式(II):
S1+S2+(V1+V2)/2<35・・・(II)
の関係を満たすことを特徴とする。
重合体のブタジエン部分のビニル結合量を赤外法(モレロ法)により求めた。
ゲルパーミエーションクロマトグラフィー[GPC:東ソー製HLC−8020、カラム:東ソー製GMH−XL(2本直列)、検出器:示差屈折率計(RI)]で単分散ポリスチレンを基準として、各重合体のポリスチレン換算の重量平均分子量(Mw)を求めた。
乾燥し、窒素置換した800mLの耐圧ガラス容器に、シクロへキサン300g、1,3-ブタジエン50g、ジテトラヒドロフリルプロパン0.66mmolを注入し、更にn-ブチルリチウム(n-BuLi)0.500mmolを加えた後、50℃で1.5時間重合反応を行った。この際の重合転化率は、ほぼ100%であった。その後、重合反応系に、2,6-ジ-t-ブチル-p-クレゾール(BHT)のイソプロパノール溶液(BHT濃度:5質量%)0.5mLを加えて、重合反応を停止させ、更に常法に従って乾燥して重合体(A-1)を得た。
乾燥し、窒素置換した800mLの耐圧ガラス容器に、シクロへキサン300g、1,3-ブタジエン50g、ジテトラヒドロフリルプロパン0.11mmolを注入し、更にn-ブチルリチウム3.6mmolを加えた後、50℃で5.0時間重合反応を行った。この際の重合転化率は、ほぼ100%であった。その後、重合反応系に、2,6-ジ-t-ブチル-p-クレゾール(BHT)のイソプロパノール溶液(BHT濃度:5質量%)0.5mLを加えて、重合反応を停止させ、更に常法に従って乾燥して重合体(B-1)を得た。
n-ブチルリチウムの使用量を変えた他は、上記重合体(B-1)と同様にして重合体(B-2)〜(B-3)を合成した。
JIS K6300−1994に準拠し、130℃にてゴム組成物のムーニー粘度[ML1+4/130℃]を測定し、参考例1のゴム組成物のムーニー粘度を100として指数表示した。なお、指数値は、105を超えると硬すぎ、また95未満では柔らかすぎるため、いずれの場合も、加工性を保持するには好ましくない。
クロロホルムを溶媒として、加硫ゴムのサンプルをソックスレー抽出器により48時間抽出し、加硫ゴムサンプルの残量より、低分子量重合体成分(B)の質量に対する加硫ゴムのクロロホルム抽出量(質量%)を求めた。
レオメトリックス社製の粘弾性測定装置を用いて、温度−20℃、周波数10Hz、歪0.1%で貯蔵弾性率(G´)を測定し、参考例1のゴム組成物の貯蔵弾性率(G´)の逆数を100として指数表示した。指数値が大きい程、貯蔵弾性率が低く、氷上性能に優れることを示す。
レオメトリックス社製の粘弾性測定装置を用い、温度0℃、周波数10Hz、歪0.1%でtanδを測定し、参考例1のゴム組成物のtanδを100として指数表示した。指数値が大きい程、ウェット性能に優れることを示す。
ランボーン型摩耗試験機を用い、室温におけるスリップ率40%での摩耗量を測定し、参考例1の摩耗量の逆数を100として指数表示した。指数値が大きい程、摩耗量が少なく、耐摩耗性に優れることを示す。

*3 デグッサ社製,Si69.
*4 ISAF,シースト3H,東海カーボン(株)製.
*5 IPPD,N-イソプロピル-N'-フェニル-p-フェニレンジアミン.
