| 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 [2,3]. To address pharmacological, biomedical, environmental and agricultural concerns, the issue of sustainability and ever-limited petroleum resources, aliphatic polyesters such as polyglycolide, polylactides (PLA), poly(ε-caprolactone) (PCL) have received considerable interests in polymer science [3]. In this work, a series of poly(ε-caprolactone)s with different arm length were synthesized through ring-opening polymerization of ε-caprolactone with 2-[(4-fluorobenzyl)thio]ethanol (1) [4] and 3-[(4-fluorobenzyl)thio]propan-1-ol (2) as the initiators, Sn(Oct)2 as a catalyst under inert atmosphere in bulk at 115 °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, DSC techniques. |
