    摘要: A process for the preparation of hydrocarbon solutions of monofunctional ether initiators of the following general structure: M--Z--O--C(R.sup.1 R.sup.2 R.sup.3) wherein M is an alkali metal; Z is a branched or straight chain hydrocarbon group which contains 3-25 carbon atoms, optionally containing aryl or substituted aryl groups; and R.sup.1, R.sup.2, and R.sup.3 are independently selected from hydrogen, alkyl, substituted alkyl groups containing lower alkoxy, lower alkylthio, and lower dialkylamino groups, aryl or substituted aryl groups containing lower alkoxy, lower alkylthio, and lower dialkylamino groups, and their employment as initiators in the anionic polymerization of olefin containing monomers in an inert, hydrocarbon solvent comprising reacting an omega-protected-1-haloalkyl with lithium metal dispersion having a particle size between 10 and 300 millimicrons in size, at a temperature between 35.degree. and 130.degree. C. in an alkane solvent containing 5 to 10 carbon atoms.
