Surface Orientation of Phenyl Groups in Poly(sodium 4-styrenesulfonate) and in Poly(sodium 4-styrenesulfonate):Poly(3,4-ethylenedioxythiophene) Mixture Examined by Sum Frequency Generation Vibrational Spectroscopy
Sum frequency generation (SFG) vibrational spectroscopy was used to investigate the surface phenyl ring orientations of spin-coated poly(sodium 4-styrenesulfonate) (PSSNa) and of PSSNa in the spin-coated polymer material Baytron P. Baytron P is a commercially available conducting polymer suspensionwith poly(3,4 ethylenedioxythiophene) (PEDOT) and PSSNa in water, which is widely used in organ...

Core-shell-corona micellar complexes between poly(ethylene glycol)-block-poly(4-vinyl pyridine) and polystyrene-block-poly(acrylic acid)
onlinelibrary.wiley.com/doi/10.1002/macp.200500368/abstract
The complexation between polystyrene-block-poly(acrylic acid) (PS-b-PAA) micelles and poly(ethylene glycol)-block-poly(4-vinyl pyridine) (PEG-b-P4VP) is studied and a facile strategy is proposed to prepare three-layered core–shell–corona micellar complexes. Micellization of PS-b-PAA in ethanol gives rise to spherical core&nda...

Preparation of ABC Star-shaped Copolymers of [Poly(styrene)- Poly(ethylene oxide)-Poly(glycidol)] Using Ethoxyethyl Glycidyl Ether as Cap Molecule.
The 3-miktoarm star-shaped ABC copolymers of polystyrene–poly(ethylene oxide)–poly(ethoxyethyl glycidyl ether) (PS-PEO-PEEGE) and polystyrene–poly(ethylene oxide)–polyglycidol (PS-PEO-PG) with low polydispersity indices (PDI1.12) and controlled molecular weight were synthesized by a combination of anionic polymerization with ring- opening polymerization. The polystyryl lit...

Methoxy poly(ethylene glycol)-b-poly(octadecanoic anhydride)-b-methoxy poly(ethylene glycol) amphiphilic triblock copolymer nanopartiles as delivery vehicles for paclitaxel
A series of amphiphilic triblock copolymers, methoxy poly(ethylene glycol)-b-poly(octadecanoic anhydride)-b-methoxy poly(ethylene glycol) (mPEG-b-POA-b-mPEG), were prepared via melt polycondensation of methoxy poly(ethylene glycol) (mPEG) and poly(octadecanoic anhydride) (POA). mPEG-b-POA-b-mPEG were characterized by FTIR, 1H-NMR, GPC, DSC and XRD. Stable drug-loaded mPEG-b-POA-b-mPEG nanoparticle...

Synthesis and aqueous phase behavior of thermoresponsive biodegradable poly(D,L-3-methylglycolide)-block-poly(ethylene glycol)-block-poly(D,L-3-methylglycolide) triblock copolymers
Novel biodegradable thermosensitive triblock copolymers of poly(D,L-3-methylglycolide)-block-poly(ethylene glycol)-block-poly(D,L-3-methylglycolide) (PMG-PEG-PMG) have been synthesized. Ring-opening polymerization of D,L-3-methyl-glycolide (MG) initiated with poly(ethylene glycol) (PEG) and Ca[N(SiMe3)(2)](2) (THF)(2) provided triblock copolymers with alternating lactyl/glycolyl sequences of contr...

Synthesis of amphiphilic poly(cyclooctene)-graft-poly(ethylene glycol) copolymers via ROMP and its surface properties
关键字：amphiphilic, poly(cyclooctene)-graft-poly(ethylene glycol), ROMP, surface properties
Macromonomer cyclooctene-poly(ethylene glycol) (cyclooctene-PEG) was first synthesized before being copolymerized with cyclooctene by ring opening metathesis polymerization (ROMP) to obtain an amphiphilic graft copolymer (poly(cyclooctene)-g-PEG) with polycyclooctene as the hydrophobic trunk chain and PEG as hydrophilic side chains. The structure of poly(cyclooctene)-g-PEG copolymer...
