Synthesis and Characterization of Poly(ethylene-co-vinyl alcohol)-graft-poly(ε-caprolactone)
Graft poly(ε-caprolactone)s (PCLs) with high graft density were synthesized by using random copolymer poly(ethylene-co-vinyl alcohol) (EVOH) to initiate ring-opening polymerization of ε-caprolactone, with and without cocatalyst Sn(Oct)2. The graft copolymer were characterized by IR, 1H and 13C NMR. The solution property and the crystallization behavior were also investigated.
متن کاملAmphiphilic copolymers of ε-caprolactone and γ-substituted ε- caprolactone. Synthesis and functionalization of poly(D,L-lactide) nanoparticles
Fully biodegradable and surface-functionalized poly(D,L-lactide) (PLA) nanoparticles have been prepared by a co-precipitation technique. Novel amphiphilic random copolyesters P(CL-co-γXCL) were synthesized by controlled copolymerization of ε-caprolactone and ε-caprolactone substituted in the γ-position by a hydrophilic X group, where X is either a cationic pyridinium (γPyCL) or a non-ionic hydr...
متن کاملPreparation and Characterization of Nanoparticles Using Poly(N-isopropylacrylamide)- Poly(ε-caprolactone) and Poly(ethylene glycol)-Poly(ε-caprolactone) Block Copolymers with Thermosensitive Function
Thermosensitive nanoparticles were prepared via the self-assembly of two different poly(ε-caprolactone)-based block copolymers of poly(N-isopropylacrylamide)-b-poly(ε-caprolactone) (PNPCL) and poly(ethylene glycol)-b-poly(ε-caprolactone) (PEGCL). The self-aggregation and thermosensitive behaviors of the mixed nanoparticles were investigated using 1H-NMR, turbidimetry, differential scanning micr...
متن کاملSynthesis, characterization and photopolymerization of vinyl functionalized poly (ε-caprolactone)
Vinyl functionalized poly (ε-caprolactone) with molar mass ranging from 500–5000 Da were synthesized by ring opening polymerization and further photopolymerized. One-step synthesis and functionalization is achieved based on ring opening polymerization (ROP). Hydroxyl butyl vinyl ether (HBVE) was employed to play the role as the initiator of ROP, and photo-curable functional group. The presence ...
متن کاملSynthesis and evaluation of triazole-linked poly(ε-caprolactone)-graft-poly(2-methyl-2-oxazoline) copolymers as potential drug carriers.
Well-defined graft copolymers were obtained using a copper-catalysed azide-alkyne Huisgen's cycloaddition click reaction from both biocompatible and non-toxic poly(ε-caprolactone) and poly(2-methyl-2-oxazoline) homopolymers. Resulting amphiphilic copolymers proved to form micelles that could be used as potential drug carriers.
