Bis (imino) phenoxide complexes of zirconium possess spectacular reactivity towards the
solvent-free polymerization of cyclic ester monomers and lactides. Polymerization of lactide
is living and the resulting product has exceptionally high number average molecular weights
(Mn). Polymerization of β-butyrolactone gives syndiotactic poly (3-hydroxybutyrate) with
good Mn and molecular weight distribution (MWD).
