Synthesis and characterization of biodegradable elastic poly(L-lactide-co-ε-caprolactone) copolymer |
초록 |
High molecular weight random copolymers of ε-caprolactone and L-lactide (ε-CL/L-LA) were synthesized with composition 50/50 (molar ratio in feed). The polymerization temperature was 150ºC and stannous octoate (SnOct) was used as a catalyst. Molecular weight of copolymers was investigated by gel permeation chromatography (GPC) and intrinsic viscosity of copolymers. The copolymers were analyzed using differential scanning calorimetry (DSC), nuclear magnetic resonance (NMR) spectroscopy, and tensile testing. The copolymers differed widely in their physical characteristics, ranging from weak to strong elastomeric character according to the molecular weight of copolymers. The good mechanical properties of the 50/50 copolymer make it suitable material for several biomedical applications that require elasticity and biodegradability. |
