[JPS Part A] Poly(vinylphosphonate)s functionalized polymer microspheres via rare earth metal-mediated group transfer polymerization
We demonstrate a facile, yet efficient method for the
functionalization of crosslinked polystyrene (PS) microspheres
with biocompatible poly(vinylphosphonate)s via the combination
of a UV grafting polymerization and a surface-initiated group
transfer polymerization. Self-initiated photografting and photopolymerization
of ethylene glycol dimethacrylate results in direct
photografting of poly(ethyle...

Nanostructured Metal/Carbon Composites from Heterobimetallic Block Copolymers with Controlled Magnetic Properties
We reported the utilization of a series of heterobimetallic diblock copolymers to prepare different iron?cobalt/carbon and iron?cobalt phosphide/carbon magnetic materials. Through the control of compositions of ferroceneand cobaltocenium-containing blocks, a transition of final inorganic materials from metal phosphide to metal alloy was observed. These metal eleme...

Preparation of Graphene-Oxide/Polyamidoamine Dendrimers and Their Adsorption Properties toward Some Heavy Metal Ions
Graphene oxide/polyamidoamine dendrimers (GO/PAMAMs)were prepared via a “grafting to” method. The adsorption behavior of the GO/PAMAMs for Pb(II), Cd(II), Cu(II), and Mn(II) was studied, and the effects of solution pH, adsorption time, and initial metal ion concentration on adsorption capacity of the adsorbent were also investigated. The pseudo-first-order and pseudo-second-order ...

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 ...

A facile method for synthesis of Fe3O4@Polymer microspheres and their application as magnetic support for loading metal nanoparticles
In this Article, a facile and general method was afforded to prepare magnetite/polymer coreshell microspheres. The hydrogen bond interaction between the magnetite and a series of functional monomers was strong enough for coating polymer shells onto the magnetite microspheres. Various functional shells such as carboxyl, hydroxyl, amide, and ester were provided via the tune of the monomer during th...

Hybrid Nanorattles of Metal Core and Stimuli-Responsive Polymer Shell for Confined Catalytic Reactions
Narrowly-dispersed silver@silica@poly(methacrylic acid) (Ag@SiO2@PMAA) core–double shell hybrid nanoparticles (NPs) were first synthesized by distillation–precipitation polymerization, using silver@silica core–shell NPs from the sol–gel reaction as templates. Selective removal of the inorganic silica inner-shell from the Ag@SiO2@PMAA core–double shell hybrid NPs by HF etching produces the Ag@...

Multicarboxylic hyperbranched polyglycerol modified SBA-15 for the adsorption of cationic dyes and heavy metal ions from aqueous media
The aim of the present work was to investigate the potential of multicarboxylic hyperbranched polyglycerol
(HPG) modified mesoporous SBA-15 (SBA/HPG-COOH) as adsorbent for the removal of cationic dyes
or/and heavy metal ions from aqueous media. The SBA/HPG-COOH adsorbents can be facilely synthesized
through two steps: in situ anionic ring-opening polymerization of glycidol and further modification...

[Materials Chemistry and Physics] Controlled growth of metal nanoparticles on amino-functionalized polystyrene microspheres and their application in surface-enhanced Raman spectroscopy
This paper describes the preparation of hybrid materials of metallic nanoparticles (NPs) coated amino-terminated polystyrene (PS-NH2) microspheres by seed-mediated growth technique, and their application in surface-enhanced Raman spectroscopy (SERS). In our approaches, monodisperse PS microspheres are firstly prepared using dispersion polymerization with a subsequent nitration and amination to ach...

Role of zinc chloride and complexing agents in highly active double metal cyanide catalysts for ring-opening polymerization of propylene oxide
Several double metal cyanide (DMC) catalysts based on Zn3[Co(CN)6]2 were prepared by an impregnation method. Infrared spectroscopy (IR),wide-angle X-ray diffraction (WAXD), and elemental analysis were used to characterize these DMC catalysts. The WAXD patterns showed that pure Zn3[Co(CN)6]2 had very high crystallinity (98.8%) with a typical cubic lattice structure, while DMC catalysts prepared w...
