Recent developments in the macromolecular engineering of aliphatic polyesters have been
overviewed. First, aluminum alkoxides mediated living ring opening polymerization (ROP)
of cyclic (di)esters, ., lactones, lactides, glycolide, is introduced. An insight into this so-
called “coordination-insertion” mechanism and the ability of this living polymerization
process to prepare well-defined homopolymers, telechelic polymers, random and block co-
polymers is then discussed. In the second part, bination of the living ROP of (di)lac-
tones with other well-controlled polymerization mechanisms such as anionic, cationic, free
radical, and metathesis polyadditions of onomers, as well as polyconden-
sations, is reported with special emphasis on the design of new and well-tailored macromo-
lecular architectures. As a result of the above synthetic breakthrough, a variety of novel ma-
terials have been developed with versatile applications in very different fields such as bio-
medical and microelectronics.
