摘要：
The invention relates to an efficient polymerization process and its use to produce novel copolymers with a specific micro structure. In particular, the invention relates to butyl rubbers with novel micro structure, preferably those obtainable by copolymerization of monomer mixtures comprising isobutylene and isoprene in diluents comprising 2,3,3,3 -tetrafluoro-1-propene. In a further aspect the invention relates to halogenated copolymers obtainable from such novel copolymers by halogenation.
