Anionic polymerization initiators useful in the preparation of polymers having a protected amine functional group. The amine functionality includes a first protecting group, which can be aralkyl, methyl, allyl or tertiary alkyl group. The other of the amine protecting groups can be the same as the first protecting group. Alternatively, the second protecting group can be different from the first protecting group, in which case it is selected to have differential stability to agents used to remove the aralkyl, methyl, allyl or tertiary alkyl protecting group.

Protected aminofunctionalized polymerization initiators and methods of making and using same

The present invention provides protected functionalized polymerization initiators having less than one molar equivalent chain extension agent introduced therein to provide hydrocarbon solubility.

Chain extended functionalized initiators and methods of preparing and using the same

Processes for the preparation of haloalkylamines and tertiary aminoalkylorganometallic compounds are disclosed. The haloalkylamines can be prepared by direct reaction of an amine with an &agr;,&ohgr;-dihaloalkane or an &agr;,&ohgr;-dihaloalkene. Tertiary aminoalkylorganometallic compounds can be prepared by reacting selected tertiary haloalkylamines with an alkali metal at a temperature greater than 45&deg; C. in hydrocarbon solvents.
