摘要： A process for manufacturing a star shaped block polymer of formula (PA--PB--PC).sub.n --N--(PD--PE).sub.m wherein PA, PB and PC are respectively vinylaromatic/methacrylic blocks, acrylic blocks and methacrylic blocks. PD is a polymer block selected from vinylaromatic and/or methacrylic monomer units, PE is an acrylic polymer block, n is 2 to 20 and m is 0 to 18 with the proviso that m+n is .ltoreq.20. The process proceeds by anionic polymerization in the presence of a monofunctional initiator of formula (II), (R).sub.p --M wherein M is an alkali or alkaline earth metal, p is 1 or 2 and R is a straight or branched alkyl radical having 2 to 6 carbon atoms or a C.sub.1 to C.sub.6 substituted alkyl radical.
