| Abstract |
The present invention provides a novel dicarbanionic initiator of formula I . The present process further provides a process for the preparation of dicarbanionic initiator of formula I comprising reacting 1 bromo 4 4 bromophenoxy 2 pentadecyl benzene of formula II with alkyllithium compound for an effecting halogen lithium exchange reaction of 1 bromo 4 4 bromophenoxy 2 pentadecyl benzene with sec butyllithium in the presence of a non polar solvent at a temperature in the range of 0 to 25°C and its use as an initiator for the synthesis of telechelic polydienes and polystyrenes and SBS or SIS triblock copolymers |
