    摘要: Compositions including one or more anionic polymerization initiators and one or more additives for improving functionalizing efficiency of living polymer anions are disclosed. The present invention also provides compositions including one or more electrophiles and one or more additives for improving functionalizing efficiency of living polymer anions. Novel electrophiles and processes for improving polymer anion functionalization efficiencies are also disclosed. The additives are generally alkali metal halides or alkoxides, and the initiators are generally organs alkali metal compounds, particularly alkyl lithium compounds.
