Description
エラストマー-X-(OR)n
エラストマー:共役ジエンのホモポリマーまたは共役ジ
エンとビニル芳香族モノマーとのコポリ
マー
X:Si、Ti、AlまたはBよりなる金属
R:C1〜C4のアルキル基
n:Si、Tiの場合は3、Al、Bの場合は2
で表わされると記載されている(請求項5、段落〔0014〕)。
アニオン性重合開始剤の存在下で、ビニル芳香族モノマー、共役ジエンモノマーまたはこれら両者を重合反応させ、そこにハロゲン化アルミニウム化合物を添加して重合反応を停止させた後、炭素数1〜4の低級アルコールと反応させて末端変性ポリマーを製造する方法によって達成される。
1)開始剤がモノマーに対して求核攻撃することによって生長種が生成する。
2)その生長種がさらにモノマーに対して求核攻撃し、その過程を繰り返すことによって生長末端を有するポリマーが生成する。
3)ポリマー末端の生長種が停止剤に対して求核攻撃し、重合が停止する。
その結果、1本のポリマー鎖には開始末端と停止末端がそれぞれ1個づつ導入されることになる。従って、本来開始剤に対して理想的には停止剤を1:1つまり100%の割合で使用することになるが、今回用いる停止剤はAlX3つまり3価であることを考慮し、その下限値を約33モル%としている。また、アルコキシル基を形成させるのに用いられる低級アルコール量は、末端基として導入されたハロゲン基を完全にアルコキシル基に変換させるのに十分な量である。
(RO)3Si(CH2)3-(S)n-(CH2)3Si(OR)3
R:炭素数1〜2のアルキル基
n:1〜4の整数
例えばビス(3-トリエトキシシリルプロピル)テトラスルフィド、ビス(2-トリエトキシシリルエチル)テトラスルフィド、ビス(3-トリメトキシシリルプロピル)テトラスルフィド、ビス(3-トリエトキシシリルプロピル)ジスルフィド等が好んで用いられる。

以上の各成分の内、加硫促進剤および硫黄を除く各成分を1.7L密閉式バンバリーミキサ中で5分間混練し、混練物を混合機外に放出して室温迄冷却した後、同じバンバリーミキサを用いて、加硫促進剤および硫黄を混合した。得られた未加硫ゴム組成物を150℃で30分間プレス加硫し、加硫ゴムを得た。
ムーニー粘度(ビスML1+4〔M〕):108
JIS K6300準拠
通常は指標が小さいもの程粘度が低く、加工性にすぐれているが、今
回は逆数をとっているため、大きい方がすぐれる
RPA(加硫ペイン効果):104
ISO 11345準拠
指標が小さい程ペイン効果が大きく、シリカの分散性が良好である
引張強度:96
JIS K6251準拠
反発弾性(40℃):99
JIS K6255準拠
全自動引張り:102
高温度引張り:118
共にISO 48に対応するJIS K6251/6301:2006準拠
指標が大きい程ゴムの伸びがよい
以上の結果から、加工性が良く、ペイン効果が高く、引張特性にすぐれたジエン系ゴム組成物が得られたことが分かる。
