Zusammenfassung:The present invention relates to a process for forming a hydrogen-mediated salt-type hydride initiated anionic polystyrene distribution through novel polymerization conditions. The invention also relates to novel hydrocarbon soluble superactive salt-type hydride catalysts and reagent compositions suitable for carrying out the hydrogen-mediated salt-type hydride initiated polymerisation of the invention. The invention also relates to novel low molecular weight polystyrene polymer compositions formed solely from styrene and molecular hydrogen as monomers. 本发明涉及通过新型聚合条件形成氢介导的盐型氢化物引发的阴离子聚苯乙烯分布的方法。本发明还涉及新型烃可溶性超活性盐型氢化物催化剂和适用于进行本发明的氢介导的盐型氢化物引发的聚合的试剂组合物。本发明还涉及仅由苯乙烯和分子氢作为单体形成的新型低分子量聚苯乙烯聚合物组合物。
