This invention further relates to polystyrene compositions having greatly improved micro- IN structures free of co-product polymer chain distributions. This invention also relates to novel hydrocarbon soluble saline hydride IN C catalyst and reagent compositions useful in conducting the hydrogen mediated saline hydride initiated polymerizations of this inven - N tion. This invention further relates to hydrocarbon soluble lithium hydride catalysts and reagent compositions formed from dimethyl - 0 aminoethanol, an alkyllithium reagent and molecular hydrogen. It also relates to the catalyst forming processes, the use of the cata- ,1 . lyst in hydrogen mediated anionic polymerization of styrene (HMAPS) and the resulting low molecular weight polystyrene distribu- tions of low asymmetry and high \"head to tail\" microstructure.
