Description
本発明は、一般的に、ポリブタジエンの製造方法に関し、より詳しくは、高いcis−1,4−含有量を有するポリブタジエンゴムの製造方法に関する。
高いcis−1,4−ポリブタジエンから得られるゴム製品[PBR]は、反発弾性が高く、発熱性(heat build-up)が低く、耐摩耗性が高い等の優れた特性により、タイヤや他のゴム製品に広範に使用されている。
本発明の目的は、バッチまたは連続操作法を用いた低ゲルの、高cis−1,4−ポリブタジエンの調製方法を提供することである。
1,3−ブタジエンの重合は、コバルト化合物および1以上のアルミニウム化合物を含む触媒の存在下で行われる。本発明の改善は、ブタジエン−溶媒フィード(butadiene-solvent feed)、水、アルキルアルミニウム化合物、コバルト触媒を、順次、反応容器に添加することを有する。モノマーの添加は、また、最後に行われてもよい。芳香族またはpi−電子供与性溶媒の使用は必要ない(de-necessitated)。
本発明は、1,3−ブタジエンを重合して主成分(96%以上)としてcis−1,4−ポリブタジエンを含むポリブタジエンゴム製品の製造する改善された方法に関するものであり、ゲル含有量を実質的に減少することを特徴とする。得られる重合体の分子量の制御は、脂肪族溶媒を使用することによる、モノマー、触媒、共触媒、促進剤の特定の添加順序によって達成される。本発明の方法は、使用する触媒の熟成(ageing)を必要としないことにより一般的な方法と区別される。加えて、1−ブテン等の高価な希釈剤/共溶媒を使用しない。
表1は、実質的にゲルを含まない、cis−1,4−ポリブタジエンを最終産物として得る本発明の様々な実施形態を説明するものである。
Claims (8)
- 少なくとも一のコバルト有機触媒、少なくとも一のアルキルアルミニウム共有機触媒、水、少なくとも一の連鎖移動剤および非発癌性溶媒系の存在下でcis−1,3−ブタジエンを重合することを有する高cis−1,4−ポリブタジエンゴムの調製方法であって、前記非発癌性溶媒はシクロヘキサンであり、前記高cis−1,4−ポリブタジエンゴムの調製は、重合調節剤を強制的に使用する(mandating use)または水、アルキルアルミニウム共触媒及びコバルト有機触媒からなる触媒組成物を熟成する(ageing)ことなく、得られる重合体のゲル含有量が実質的に低いことによるものであり、
