Aromatic-Aliphatic Block Copolyesters Based on AA/BB Polymers and Poly(lactic) Acid
Polymers and High Performance Materials
Aromatic/aliphatic poly[L-lactide-b-(ethyleneoxyethylene terephthalate-co-adipate)-b-L-lactide] triblock copolymers were synthesized and characterized. Hydroxy-telechelic poly(ethyleneoxyethylene terephthalate-co-adipate) (PEOETA) was first prepared via polycondensation and then utilized as an initiator for the ring opening polymerization (ROP) of L-lactide (LLA) in the presence of stannous octanoate (Sn(Oct)2). Formation of the block copolymer was confirmed by 1H NMR spectroscopy, GPC, and AFM. The polymerization rate induced by the PEOETA macroinitiator was comparable to that of a small molecule initiator.
