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 CS or greater initiator having a tertiary halide.
L'invention concerne un nouveau système catalyseur qui améliore le potentiel de transfert thermique d'un système de traitement de suspension de réaction butylique dans la production de polymères à base d'isobutylène en processus de polymérisation continue de suspension. On conduit le procédé de polymérisation dans un système de polymérisation anhydre qui renferme un mélange de monomères dans un diluant polaire, avec un acide de Lewis et un C¿5? ou initiateur supérieur à halogénure tertiaire.
