A process for the preparation of hydrocarbon solutions of monofunctional ether initiators of the following general structure: M-Qn-Z-O-[A(R<1>R<2>R<3>)] wherein M is an alkali metal selected from the goup consisting of lithium, sodium and potassium; Q is a saturated or unsaturated hydrocarbyl group derived by incorporation of a compound selected from the group consisting of conjugated diene hydrocarbons, alkenylsubstituted aromatic hydrocarbons, and mixtures thereof into the M-Z linkage; Z is a branched or straight chain hydrocarbon group which contains 3-25 carbon atoms, optionally containing aryl or substituted aryl groups; A is an element selected from carbon and silicon; R<1>, R<2>, and R<3> are independently selected from hydrogen, alkyl, substituted alkyl groups containing lower alkyl, lower alkylthio, and lower dialkylamino groups, aryl or substituted aryl groups containing lower alkyl, lower alkylthio, and lower dialkylamino groups, and n is an integer from 1 to 5, monofunctional ethers produced by the process, use of the initiators in a polymerization process and polymers produced by the polymerization process. |
