초록

중반응성 폴리부텐을 루이스산 촉매를 이용하여 합성하였다. 40~70% 비닐리덴 함량, 수평균 분자량 500~1,000 g/mol, 동점도 20~210 cSt (at 100 ℃)을 지닌 중반응성 폴리부텐은 노르말프로판올 조촉매와 삼불화붕소 주촉매로 구성된 착물촉매를 사용하여 -8~5 ℃, 2.5 kg 조건에서 가장 좋은 결과로 얻어졌다. 비닐리덴 함량은 반응 온도를 조절하여 쉽게 변화시킬 수 있었다.

Mid-range vinylidene content polyisobutylenes were prepared by using a Lewis acid catalyst. The best results were obtained when a complex catalyst composed of n-propanol as a cocatalyst and BF3 as a main catalyst was used at the reaction temperature of -8 to 5 ℃ under a pressure of 2.5 kg/cm2. The number average molecular weight (Mn) and viscosity of the polyisobutylenes were 500~1,000 g/mol and 20~210 cSt (at 100 ℃), respectively. The vinylidene content was 40~70% and easily varied by adjusting the reaction temperature.
