1. a preparation method for high-activity polyisobutylene, is characterized in that, comprises the following steps:

  • (1) by aluminum chloride and ether mixing, add thinner, be made into initiator solution I;

    (2) by iso-butylene post liquefaction, with mixing diluents, monomer solution M is made into;

    (3) monomer solution M is contacted mixing with initiator solution I in micro mixer, react in the phantastron after micro mixer, add terminator termination reaction at phantastron end;

    (4) by step (3) gained production fluid after de-thinner, drying, obtain high-activity polyisobutylene.
