    摘要: 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 250 C and its use as an initiator for the synthesis of telechelic polydienes and polystyrenes and SBS or SIS triblock copolymers.

    摘要: A novel process for coupling living polymers containing terminal (meth)acrylic units, which enables an increase in molecular weight and/or a defined multisequencing and/or a star structure with a defined number of branches, is disclosed. The disclosed process comprises the steps of: (i) anionic polymerization using an initiator system consisting of a functional initiator and a ligand to obtain a living polymer containing living terminal (meth)acrylics units; (ii) reacting it with an aldehyde compound of formula R--(CHO).sub.r in which r.gtoreq.2; and (iii) recovering the final polycondensate by means known per se.
