Abstract
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.
