| Proje Konusu | Ring-opening polymerization (ROP) can be performed both in a controlled and living manner, depending on the monomer and initiator/catalyst system [1]. Aliphatic polyesters, synthesized via (ROP) of lactones and lactides, are of significant interest owing to good mechanical properties, hydrolyzability and biocompatibility [2]. Among aliphatic polyesters such as polyglycolide, poly(ε-caprolactone) (PCL), poly(L-lactide) (PLLA), is one of the most promising polymers which could be produced from renewable sources such as starch[3]. In this work, a series of poly(L-LA)s with different arm length were synthesized through ring-opening polymerization of L-lactide with 2-[(pentafluorobenzyl)thio]ethanol (1) and 3-[(pentafluorobenzyl)thio]propan-1-ol (2) as the initiators, Sn(Oct)2 as a catalyst under inert atmosphere in toluene at 120 °C. The route followed during synthesis of initiators and polymers is given in Scheme 1. The synthesized initiators and polymers were characterized by FT-IR and NMR spectral data and GPC technique.
