Synthesis and Characterization of Poly(L-Lactide-ran-ε-Caprolactam) Copolymer by Ring Opening Polymerization |
초록 |
Poly(L-lactide)(PLLA) is attractive material due to biocompatible and biodegradable and pharmaceutical applications, but mechanical properties of PLLA are not sufficient. Random copolymers of Poly(L-Lactide-ran-ε-Caprolactam) were synthesized by ring opening polymerization to improve mechanical properties. A process was carried out via bulk polymerization in the presence of initiator 6-aminocaproic acid and catalyst tin octoate. 6-aminocaproic acid was used as initiator of ε-caprolactam and tin octoate was used as catalyst of L-lactide. The characters of copolymers were evaluated by means of DSC, TGA, gel permeation chromatography (GPC) and 1H-NMR spectra. The varied molecular weight copolymers could be obtained within specific range of ratio between L-lactide and ε-caprolactam. The higher moiety of L-lactide led to the higher average molecular weight of copolymers. |
