A facile approach to biodegradable poly(e-caprolactone)- poly(ethylene glycol)-based polyurethanes containing pendant amino groups
A novel biodegradable poly(e-caprolactone)-poly(ethylene glycol)-based polyurethanes (PCL-PEG-PU) with pendant amino groups was synthesized by direct coupling of PEG ester of NH 2 -protected-(aspartic acid) (PEG-Asp-PEG diols) and poly(e-caprolactone) (PCL) diols with hexamethylene dissocyanate (HDI) under mild reaction conditions and by sub- sequent deprotection of benzyloxycarbonyl (Cbz) gr...

Novel biodegradable poly(ethylene glycol)-block-poly(2-methyl-2- carboxyl-propylene carbonate) copolymers: Synthesis, characterization, and micellization
A novel amphiphilic biodegradable poly(ethylene glycol)–poly(2-methyl-2-carboxyl-propylene carbonate) (MPEG–PMBC) block copolymer was successfully synthesized by ring-opening polymerization (ROP) of 2-methyl-2-carboxyl-propylene carbonate (MBC) with MPEG as a macroinitiator. 13 C NMR and GPC con?rmed its structure. It could self-assemble into micelles in aqueous solution with the cr...

Synthesis and characterization of novel biotinylated biodegradable poly(ethylene glycol)-b-poly(carbonate-lactic acid) copolymers
Poly(ethylene glycol)-b-poly(5-benzyloxy-trimethylene carbonate-lactic acid) copolymers (PEG-b-P(BTMC-LA)) were synthe- sized by ring-opening polymerization of lactide and 5-benzyloxy trimethylene carbonate in the presence of mono-hydroxyl poly(eth- ylene glycol) with diethyl zinc as catalyst. They were further converted into deprotected copolymers with the pendant hydroxyl groups by hydrogenol...

Anti-tumor Drug Delivery of pH-Sensitive (PEG)-Poly(L-Histidine-)- Poly(L-Lactide) Triblock Nanoparticles
pH-sensitive poly(ethylene glycol)-poly(L-histidine)-poly(L-lactide) (PEG-PH-PLLA) nanoparticles were prepared and used as carriers for anti-tumor drug delivery. The morphology and properties of the nanoparticles such as pH sensitivity, zeta potential and mean diameters were investigated. The cytotoxicity of PEG-PH-PLLA nanoparticles was evaluated. Doxorubicin (DOX) was encapsulated in the nanopar...

“Study on the Phase Transition Behavior of Poly(butylene adipate) in its Blends with Poly(vinyl phenol)”
The phase transition behavior of poly(butylene adipate) (PBA) crystals in its blends with poly(vinyl phenol) (PVPh) was investigated by infrared (IR) spectroscopy and X-ray diffraction (XRD). The IR and XRD studies indicate that the hydrogen bonding between the C═O group of PBA and the OH group of PVPh developed in the PBA/PVPh blends with the ratios of 80/20 and 50/50 does not influence the solu...

Fe3O4@poly(2-hydroxyethyl methacrylate)-graft-poly(ε- caprolactone) magnetic nanoparticles with branched brush polymeric shell
Well-defined monodisperse Fe3O4@poly (2-hydroxyethyl methacrylate)-graft- poly(e-caprolactone)( Fe3O4@PHEMA-g-PCL) magnetic nanoparticles with novel topological structure, i.e., with branched brush polymeric shell, were successfully prepared by the combination of atom transfer radical polymerization(ATRP) and ring-opening polymerization (ROP). Oleic acid stabilized monodisperse Fe3O4 nanoparticle...
