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.
