Synthesis and properties of gel polymer electrolyte membranes based on novel comb-like methyl methacrylate copolymers
Based on the principle of molecular design,
three comb-like methyl methacrylate copolymer matrixes for gel polymer
electrolyte (GPE) were designed and synthesized by reacting methyl
methacrylate-maleic anhydride copolymer (P(MMA-MAh)) with poly(ethylene glycol)
monomethyl ether (PEGME) of different molecular weight (350, 600, and 750)
respectively. The structures of comb-like polymers were chara...

Structure and Properties of an Organic Rectorite/ Poly(methyl methacrylate) Nanocomposite Gel Polymer Electrolyte byIn SituSynthesis
The synthesis of organic-modified rectorite
(OREC)/polymethyl methacrylate (PMMA) nanocomposite gel polymer electrolyte
(NGPE) viain situ polymerization was investigated using free radical initiator
in an solution, in which organic plasticizer, propylene carbonate(PC) acted as
a solvent. A serious of NGPE membranes with different OREC content were
prepared and characterized.The dispersion and ex...

Determination of the interaction using FTIR within the components of GPE based on the synthesized grafted polymer
An oxyethylene chain (–CH2–CH2–O–) grafted polymer
(P(MMA–MAh)–PEGME) was synthesized by reacting poly(ethylene glycol) monomethyl
ether (PEGME) with the copolymer of poly(methyl metacrylate–maleic anhydride)
(P(MMA–MAh)) and endcapping the residual carboxylic acid with methanol.
Rectorite modified with dodecyl benzyl dimethyl ammonium chloride (OREC) was
used as a filler additive to mod...

A Supramolecular Janus Hyperbranched Polymer and Its Photoresponsive Self-Assembly of Vesicles with Narrow Size Distribution
Herein, we report a novel Janus particle and supramolecular block copolymer consisting of two chemically distinct hyperbranched polymers, which is coined as Janus hyperbranched polymer. It is constructed by the noncovalent coupling between a hydrophobic hyperbranched poly(3-ethyl-3-oxetanemethanol) with an apex of an azobenzene (AZO)
group and a hydrophilic hyperbranched polygl...

Modification of Metal Complex on Hydrogenation of o-Chloronitrobenzene over Polymer-stabilized Platinum Colloidal Clusters
The effect of metal complex on hydrogenation of o-chloronitrobenzene CNB. over poly-vinylpyrrolidone-stabilized platinum clusters PVP-Pt. has been studied in methanol at 303 K and atmospheric pressure. The addition of metal complexes to the catalytic system can considerably modulate both the activity and the selectivity of the catalyst. A low activity 0.41 mol H2rmol Pt s. and low selectivity ...

Narrow-dispersed Crosslinked Core-shell Polymer Microspheres Prepared by Surface-initiated Atom Transfer Radical Polymerization
Grafting of polystyrene with narrowly dispersed polymer microspheres through surface-initiated atom transfer radical polymerization (ATRP) was investigated. Polydivinylbenzene (PDVB) microspheres were prepared by dispersion polymerization with poly(N-vinyl pyrrolidone) (PVP) as stabilizer. The surfaces of PDVB microspheres were chloromethylated by chloromethyl methyl ether in the presence of zinc ...

Preparation of Monodisperse Crosslinked Polymer Microspheres Having Chloromethyl Group by Distillation-precipitation Polymerization
Monodisperse crosslinked poly(chloromethylstyrene-co-divinylbenzene) (poly(CMSt-co-DVB)) microspheres were prepared by distillation-precipitation copolymerization of chloromethylstyrene (CMSt) and divinylbenzene (DVB) in neat acetonitrile. The polymer particles had clean surfaces due to the absence of any added stabilizer. The size of the particles ranges from 2.59 μm to 3.19 μm and with mono-di...

Preparation of Poly(divinybenzene-co-N-isopropylacrylamide) Microspheres and Their Hydrogen-bonding Assemble Behavior for Core-Corona Raspberry-like Polymer Composite
Narrowdisperse poly(divinylbenzene-co-Nisopropylacrylamide) (poly(DVB-co-NIPAM)) functional microspheres with the diameter in the range of 630 nm and 2.58 um were prepared by distillation–precipitation polymerization in neat acetonitrile in the absence of any stabilizer. The effect of N-isopropylacrylamide (NIPAM) ratio in the comonomer
feed on the morphology of the resultant polymer particles wa...

Narrow or Mono-Disperse Crosslinked and Functional Core-shell Polymer Particles by Two-stage Precipitation Polymerization
Narrow-disperse and monodisperse crosslinked core–shell polymer particles containing different functional groups, such as esters, hydroxyls, chloromethyls, carboxylic acids, amides, cyanos, and glycidyls, in the shell layers in the micrometer size range were prepared by a two-stage precipitation polymerization in the absence of any stabilizer. Commercial divinylbenzene (DVB), containing 80% DVB, ...

Preparation of Polymer@Titania Raspberry-like Core-corona Composite via Heterocoagulated Self-assembly based on Hydrogen-bonding Interaction
The polymer@titania core–corona composites were prepared by a heterocoagluated self-assembly of poly(4-vinylpyridine) (PVPy) core and poly(ethyleneglycol dimethacrylate-co-methacrylic acid)/titania (P(EGDMA-co-MAA)/TiO2) corona, during which the hydrogen-bonding interaction between the hydroxyl of titania corona and the pyridyl groups of the core particles played an essential role for the formati...
