NEW FUNCTIONALIZED INITIATORS FOR ANIONIC POLYMERIZATION

A process for the preparation of hydrocarbon solutions of monofunctional ether initiators of the following general structure: M-Z-O-C(R1R2R3)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 a...

Zusammenfassung:	A process for the preparation of hydrocarbon solutions of monofunctional ether initiators of the following general structure: M-Z-O-C(R1R2R3)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 R1, R2, and R3 are independently selected from hydrogen, alkyl, substituted alkyl, aryl or substituted aryl 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 DEG and 130 DEG C. in an alkane solvent containing 5 to 10 carbon atoms.
