This review describes the recent advances (from 2008 onwards) in the use of Schiff-base metal complexes as catalysts for the ring opening polymerization (ROP) of cyclic esters. The synthesis and structure of the metal complexes, as well as all aspects concerning the polymerization process and the characteristics of the polymers formed, will be discussed.

AbstractFor the purpose of increasing the hydrophilicity of polylactide, new block copolymers with protected functional groups, poly(lactide-co-(S)-b-benzyl aspartate)-poly(ethylene oxide)-poly(lactide-co-(S)- b-benzyl aspartate), were synthesized via ring-opening polymerization of D,L-lactide and (3S, 6R,S)-3- [(benzyloxycarbonyl)methyl]-6-methylmorpholine-2,5-dione in the presence of hydroxyltelechelic poly(ethylene oxide) (PEO) as an initiator at 140 °C for 24 h. The benzyl protective groups of the block copolymers were completely removed to give poly(lactide-co-(S)-aspartic acid)-PEO-poly(lactide-co-(S)-aspartic acid), (poly(DLLA-co-Asp)-b-PEO-b-poly(DLLA-co-Asp)). This shows lower crystallization and melting temperature compared with the polymers before deprotection. Poly(DLLA-co-Asp)-b-PEO-b-poly(DLLA-co-Asp) with 55.6 wt.-% of PEO is more hydrophilic, shows higher water absorption and is degraded faster than with 39.5 wt.-% of PEO.

2-(2-(Benzyloxy)ethoxy)-1,3,2-dioxaphospholane-2-oxide was developed for the ring-opening polymerization to multifunctional poly(phosphoester)s. An acetal-protected comonomer allows selective release of the hydroxyl groups by hydrolysis and hydrogenation.
