Materials based on aliphatic polyesters attract much attention due to their biodegradation and biocompatibility. The ring opening polymerization (ROP) using metal complexes as initiators is the most appropriate method for synthesis of such materials due to controlling type of process. The search of new catalysts of this polymerization is the actual task for modern organometallic chemistry. In our work we synthesized and investigated: -1) new complexes of Ti, Al, Zn based on dialkanolamines, pyridine containing alcohols and substituted diethylenetriamines. The complexes of presented type are active initiators of ROP of lactide and ε-caprolactone. -2) mixed complexes of Al, Zn containing iminophenolate ligands and fragments of functionalized unsaturated alcohols. These compounds were used as catalysts in ring opening polymerization of cyclic lactones. The fragment of unsaturated alcohol is transferred to the end of polymer chain with high level of functionality. This synthetic strategy allows us to obtain macromonomers based on biodegradable materials with high degree of functionalization.
