Polyisobutylene composition having internal vinylidene and process for preparing the polyisobutylene polymer composition
摘要：
A polyisobutylene composition has polyisobutylene molecules with a first portion having a alpha vinylidene molecules, a second portion having beta vinylidene molecules, and a third portion having internal vinylidene molecules. The first portion has less than 75% of the polyisobutylene molecules of the composition. A total of the first portion and the second portion is less than 90% of the polyisobutylene molecules of the composition. The third portion is more than 3% of the polyisobutylene molecules of the composition. A process for forming this polyisobutylene polymer composition passes an isobutylene through a fixed bed reactor having a boron trifluoride/alcohol complex therein so as to produce the polyisobutylene composition.
摘要（中）：

聚异丁烯组合物具有聚异丁烯分子，其第一部分具有α-亚乙烯基分子，第二部分具有β-亚乙烯基分子，第三部分具有内部亚乙烯基分子。 第一部分具有少于组合物的聚异丁烯分子的75％。 总共第一部分和第二部分小于组合物的聚异丁烯分子的90％。 第三部分是组合物的聚异丁烯分子的3％以上。 形成该聚异丁烯聚合物组合物的方法使异丁烯通过其中具有三氟化硼/醇络合物的固定床反应器，以产生聚异丁烯组合物。
