摘要: The invention relates to a new catalyst system that improves the heat transfer capability of a butyl reactor slurry process system in the production of isobutylene-based polymers in continuous slurry polymerization processes. The process is carried out in an anhydrous polymerization system containing a mixture of the monomers in a polar diluent along with a Lewis acid and a C5 or greater initiator having a tertiary halide.

摘要: The invention relates to methods for separating mixture components such as reactor effluent components. In particular, the invention relates to the use of an extractive agent such as a hydrocarbon in an extractive distillation process to separate monomers such as a C4-C7 isoolefins such as isobutylene from mixtures such as reactor effluents including one or more hydrofluorocarbon(s) (HFC).
