Abstract: The invention relates to the production of isobutylene homopolymers having a weight-average molecular weight of 75,000 to 10,000,000 by means of the polymerization of isobutylene by (a) performing the polymerization at -80°C to -190°C, (b) using optionally halogenated C
1 to C
5 hydrocarbons as an inert solvent, (c) using a Lewis acid complex as a polymerization catalyst, and (d) performing the polymerization in the presence of at least one reaction accelerator in the form of an ethylenically saturated hydrocarbon compound, which contains an oxygen atom and no proton that can be emitted, and performing the polymerization in the presence of at least one chain length regulator, which contains a tertiary olefinic carbon atom.Abstract translation: 本发明涉及通过（a）在-80℃至-190℃下进行聚合反应，（b）任选地使用异丁烯的聚合反应制备重均分子量为75,000至10,000,000的异丁烯均聚物 卤代C1至C5烃作为惰性溶剂，（c）使用路易斯酸配合物作为聚合催化剂，和（d）在至少一种烯属饱和烃化合物形式的反应促进剂存在下进行聚合， 含有氧原子并且不能发射的质子，并且在至少一个包含叔烯烃碳原子的链长调节剂的存在下进行聚合。
