Abstract
The invention relates to new polymerization processes including diluents including hydrofluorocarbons and their use to produce novel halogenated polymers with new sequence distributions. In particular, the invention relates to halogenated copolymers of an isoolefin, preferably isobutylene, and a multiolefin, preferably a conjugated diene, more preferably isoprene, with new sequence distributions.
