摘要：

The preparation of alpha,alpha,beta-trisubstituted beta-lactones has opened the route to living anionic ring-opening polymerization of these monomers. Therefore, transfer reactions due to hydrogen abstraction were limited and it is now possible to strickly control sample molecular weight. Moreover, living end-groups lead to the preparation of block co-polymers with block controlled lenghts. In the same way, high-molecular-weight statistical co-polymers have been synthesized. Hydrolyzable micelles and nanoparticles will be prepared from these co-polymers after chemical modifications to adjust the hydrophilic/hydrophobic balance.
