Abstract
공액 디엔 단량체의 음이온성 중합을 개질시키기 위해 알킬 테트라하이드로푸르푸릴 에테르와 같은 각종 화합물을 이용할 수 있음을 기대치 않게 알아냈다. 이러한 개질제들을 사용하여 이소프렌 단량체를 탁월한 중합 속도로 고함량의 3,4-폴리이소프렌으로 중합시킬 수 잇다. 상기 개질제는 이러한 중합을 개질시키기 위해 전형적으로 사용된 테트라메틸에틸렌 디아민과 같은 개질제와는 대조적이다. 더욱 특히, 본 발명은 (a)리튬 개시제 및 (b)에틸 테트라하이드로푸르푸릴 에테르 개질제로 이루어진 촉매 시스템의 존재하에, 유기 용매중에서 이소프렌 단량체를 중합시킴을 포함하는 3,4-폴리이소프렌의 합성방법을 개시하고 있다.
