Abstract:
A process for synthesizing a functionalized lithium initiator which comprises the steps of (1) reacting diisopropenylbenzene with a tertiary alkyl lithium compound in an aromatic solvent at a temperature which is within the range of about 0Â° C. to about 100Â° C. to produce a dilithium initiator; and (2) reacting the dilithium initiator with a alkylaminoaryl compound of the structural formula: wherein R, Râ€², and Râ€³ can be the same or different, wherein R is selected from the group consisting of hydrogen atoms, alkyl groups, aryl groups, alkaryl groups, and amino aryl groups, and wherein Râ€² and Râ€³ represent alkyl groups.
