Polyisobutylenes(PIBs),produced by the cationic polymerization of isobutylene(IB),have exhibited some distinguished properties [1-2] with respect to thermal stability,flexibility at ambient temperature,and impermeability to gases and so on [3-4].Compared with highly relative polyisobutylenes,few research was focused on medium molecular weight polyisobutylenes and high molecular weight polyisobutylenes,although they always have relatively high values and active demands.In this work,we established a microflow reaction system,and systematically investigates the polymerization of medium molecular weight polyisobutylenes coinitiated by neat AlCl3 in the mixture of hexane and CH2Cl2.
