A multi-arm star-shaped block copolymer was synthesized from various k
inds of multifunctional linear blocks and a dendrite polyfunctional br
anching center. Polystyrene and polyisoprene blocks with the desired l
engths were prepared by anionic polymerization of the corresponding mo
nomers initiated by sec-BuLi. The synthesis of an individual carbosila
ne dendrimer bearing active Si-CI groups in the outside layer is descr
ibed. It is shown that the multi-arm block copolymer is capable of sel
f-organization to form Spherical and cylindrical micelles.
