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.
