Junction-point-functionalized block copolymers were synthesized according to Scheme 3 [34]. Styrene was polymerized first using s-BuIi as initiator. After completion of polymerization a small excess of DMADPE was introduced to the reaction mixture (DMADPE/Ii = 1.2/1). The reaction was left for completion for 3 d at room temperature. Isoprene was then added, polymerized, and terminated by addition of degassed methanol In the case of the triblock copolymer synthesis, after completion of isoprene polymerization, a predetermined amount of a Me2SiCl2 solution in benzene was introduced to the reaction mixture (Cl/Ii = 1/2.2). The coupHng reaction was essentially complete in 3 d. Solvent/nonsolvent fractionation was employed in order to separate the triblock from excess diblock.
