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...

Raspberry-like Core-corona Polymer Composite Particles via Electrostatic Self-assembled Heterocoagulation
Nano-sized poly(ethyleneglycol dimethacrylate-co-sodium acrylate) (poly(EGDMA-co-AcNa)) particles were effectively self-assembled on poly(divinylbenzene-co-styrylmethyl trimethyl ammonium chloride) (poly(DVB-co-StMTMACl)) surfaces to result in core–corona composite particles with a raspberry-like structure by an electrostatic interaction through an affinity complex between sodium acrylate and qua...

Raspberry-like Polymer/Silica Core-Corona Composite by Self-assemble Heterocoagulation Based on A Hydrogen-bonding Interaction
Raspberry-like poly(ethyleneglycol dimethacrylate-co-4-vinylpyridine)/silica (poly(EGDMA-co-VPy)/SiO2) core-corona composite was prepared by a self-assemble heterocoagulation based on a hydrogen-bonding interaction between the pyridyl group of poly(EGDMA-co-VPy) core
and the active hydroxyl group of silica corona. The raspberrylike composite was stable near the neutral environment with pH ranging ...

Hollow Polymer Microspheres Containing Gold-nanocolloid Core Adsorbed on the Inner-surface as A Catalytic Microreactor
Hollow polymer microspheres with different polarity and functional group for the shell layer containing gold nanocolloid cores adsorbed on the inner surface were
prepared by selective removal of sandwiched silica layer from the corresponding gold/silica/polydivinylbenzene (Au/SiO2/PDVB), Au/SiO2/poly(ethyleneglycol dimethacrylate) (Au/SiO2/PEGDMA), and Au/SiO2/poly(ethyleneglycol
dimethacrylate-co...

Preparation of Narrow- or Monodisperse Polymer Microspheres with Active Hydroxyl Group by Distillation-precipitation Polymerization
Narrow-dispersion or monodisperse polymer microspheres with active hydroxyl groups were prepared by distillation–precipitation polymerization in the absence of any stabilizer. The monomer hydroxyethyl methacrylate (HEMA) was copolymerized with either commercial divinylbenzene (DVB) (containing 80 % of DVB isomers) or ethyleneglycol dimethacrylate (EGDMA) as crosslinker by distillation–precipitat...
