Amphiphilic poly{[α-maleic anhydride-ω-methoxy-poly(ethylene glycol)]-co-(ethyl cyanoacrylate)} graft copolymer nanoparticles as carriers for transdermal drug delivery
In this study, the transdermal drug delivery properties of D,L-tetrahydropalmatine (THP)-loaded amphiphilic poly{[α-maleic anhydride-ω-methoxy-poly(ethylene glycol)]-co-(ethyl cyanoacrylate)} (PEGECA) graft copolymer nanoparticles (PEGECAT NPs) were evaluated by skin penetration experiments in vitro. The transdermal permeation experiments in vitro were carried out in franz diffusion ce...

Miscibility, crystallization kinetics, crystal structure, and microstructure of biodegradable poly(butylene succinate-co-butylene adipate) (PBSA)/poly(vinyl phenol) (PVPh) blends were studied by differential scanning calorimetry, optical microscopy, wide angle X-ray diffraction, and small angle X-ray scattering in detail in this work. PBSA and PVPh are miscible as evidenced by the single composi...

Abstract
Biodegradable polymer blends of poly(3-hydroxybutyrate-co-hydroxyvalerate) (PHBV) and poly(ε-caprolactone) (PCL) blends were prepared with the ratio of PHBV/PCL ranging from 80/20-20/80 by co-dissolving the two polyesters in chloroform and casting the mixture. Differential scanning calorimetry (DSC) and optical microscopy (OM) were used to investigate the miscibility and crysta...

67. Synthesis and characterization of poly(arylene ether ketone) (co)polymers containing...... F.Wang,T.L.Chen,J.P.Xu,T.X.Liu,H.Y.Jiang,Y.H.Qi,S.Z.Liu,X.Y.Li. Polymer 47(11),4148-4153,2006.
Poly(arylene ether ketone)s containing sulfonate groups were synthesized by aromatic nucleophilic polycondensation of 4,4′-difluorobenzophenone (DFK), sodium 2,5-dihydroxybenzensulfonate (SHQ) and bisphenols. Only low-molecular weight oligomer was obtained when hydroquinone (HQ) was employed as comonomer, while copolymerization of DFK, SHQ, and phenolphthalein (PL) proceeded quantitatively to hig...

Reinforcement of shape-memory poly(ethylene-co-vinyl acetate) by carbon fibre to access robust recovery capability under resistant Condition`
关键字：Smart materials, Carbon fibresPolymer-matrix composites, Shape memory polymer
Poly (ethylene-co-vinyl acetate) (EVA), as one of commercial polymers, has been used early to fabricateshape-memory polymers (SMPs). However, its low recovery stress restricts the potential applications insome tough conditions due to its high ?exible feature. Herein, we developed a series of EVA-basedcomposites (cEVA/CF) with remarkably enhanced recovery stress both in free-state and resistant con...

Poly(L?lactic acid)-block-poly(butylene succinate-co-butylene adipate) Multiblock Copolymers: From Synthesis to Thermo-Mechanical Properties
关键字：biodegradable, multi-block copolymer, chain extension, chain coupling
Multiblock copolymers poly(L-lactic acid)-block-poly(butylene succinate-co-butylene adipate)s (abbr. P(LLA-mb-
BSA)s) are synthesized via a polycondensation/chain extension/coupling method using binary chain extenders. A poly(L-lactic acid) (PLLA) prepolymer synthesized via direct melt polycondensation of L-lactic acid is rapidly chain extended with a bis (2-oxazoline) to form hydroxyl t...

Grafting of telechelic poly(lactic-co-glycolic acid) onto O2 Plasma Treated Polypropylene Flakes
关键字：polypropylene; telechelic poly(lactic-coglycolic acid); oxygen plasma; grafting
In this work, we described a facile approach to preparing polypropylene (PP) surface functionalized with telechelic poly(lactic-co-glycolic acid) (HOPLGA-COOH). The PP flakes were first treated with oxygen plasma and then grafted with different molecular
weight PLGA (Mw ? 50, 100, and 300 K) in dry dichloromethane solution with the addition of phosphorus pentachloride (PCl...

B-11 3Q MAS NMR Study on Glucose-Responsive Micelles Self-assembled from PEG-b-P(AA-co-AAPBA)
关键字：B-11 3Q MAS NMR, coordination, glucose-responsiveness, micelles, self-assembly
Phenylboronic acid (PBA) based glucose-responsive materials have attracted great interests in recent years for developing insulin delivery systems. It is desired to obtain PBA based materials that can response to glucose under physiological pH and understand the mechanism. By using B-11 triple-quantum magic-angle spinning nuclear magnetic resonance (B-11 3Q MAS NMR) measurements, the glucose-res...

Surface modification of poly(styrene-b-(ethylene-co-butylene)-b-styrene) elastomer via UV-induced graft polymerization of N-vinyl pyrrolidone
关键字：Styrenic block copolymers, UV-induced graft polymerization, N-vinyl pyrrolidone (NVP), Hemocompatibility
Poly(N-vinyl pyrrolidone) (PNVP) was covalently grafted onto the surface of biomedical poly(styrene-b-(ethylene-co-butylene)-b-styrene) (SEBS) elastomer via a technique of UV-induced graft polymerization combined with plasma pre-treatment. The surface graft polymerization of N-vinyl pyrrolidone (NVP) was confirmed by ATR-FTIR and XPS. Effect of the parameters of graft polymerization, i...
