Magnetic Polystyrene Nanosphere Immobilized TEMPO: A Readily Prepared, Highly Reactive and Recyclable Polymer Catalyst in the Selective Oxidation of Alcohols
摘要: The 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) radical immobilized on the magnetic polystyrene nanospheres (MPNs) was used as a recyclable catalyst in the oxidation of various alcohols. The new and simply prepared heterogeneous TEMPO/MPNs exhibits both similar versatility and efficiency to homogeneous TEMPO under basic Montanari conditions. The excellent stability of the MPNs enables the T...

122. Can spherulitic growth rate accelerate before impingement for a semicrystalline polymer during the isothermal crystallization process?
Isothermal crystallization processes in the temperature range from 110 to 140 °C were studied by using polarizing optical microscopy (POM) for poly(L-lactide) (PLLA) film samples with and without confinement conditions. The PLLA film samples were prepared by melt pressing between two cover glasses to provide the surface confinements and by removing the top cover glasses or by solution cas...

Study of shear-induced interfacial crystallization in polymer-based composite through in situ monitoring interfacial shear stress
In order to further investigate shear-induced
interfacial crystallization of polymer-based composites, an
improved fiber-pulling device was designed and built. Its
peculiar characteristic is that a force transducer is assembled
to in situ monitor the variation of interfacial shear stress
between the polymer matrix and pulling fiber. Thus, the
relationship between interfacial shear stress and...

Controlled synthesis of graft polymer through the coupling reaction between the appending β-keto ester and the terminal amine
A new method to synthesize graft polymer with controlled graft density (?) through the coupling reaction between the appending β-keto ester and the terminal amine is proposed. Following this method, the backbone polymer of poly[2-(acetoacetoxy) ethyl methacrylate] (PAEMA) containing the appending β-keto ester is synthesized by reversible addition-fragmentation chain transfer polymerizati...

Robust Microsieves with Excellent Solvent Resistance: Cross-Linkage of Perforated Polymer Films with Honeycomb Structure
Polymeric microsieves with uniform and tunable pores were fabricated with the breath-figure method and sequent vulcanization procedure using commercially available block copolymer polystyrene-b-polyisoprene-b-polystyrene. Uniform pore size and small film thickness endow the microsieves with high size selectivity and low operation pressure, while the crosslinked chemical structure gives them good m...

89. A Click Chemistry Approach to The Efficient Synthesis of Polyoxometalate-Polymer Hybrids with Well-Defined Structures
In this study a click chemistry approach was used to synthesize polyoxometalate–polymer hybrids with well-defined structures. The starting materials were a two-azido-containing organosilyl derivative of a Wells-Dawson-type polyoxometalate and a propargyl-terminated poly(ε-caprolactone). The clicking reaction between the azido groups and alkynyl groups was found to be very efficient a...

87. Dynamically Confined Crystallization in A Soft Lamellar Space Constituted by Alternating Polymer Co-brushes
The originally synthesized hydrophobic hybrid polymer Bu4N+-POM-PS is tuned into a giant amphiphile composed of a hydrophilic H+-POM head and a hydrophobic PS tail through protonation. Immediately, the hybrid amphiphiles self-assemble into vesicles. A further annealing treatment induces an evolution from vesicles to tubular aggregates containing H+-POM nanotubes wrapped with PS coronas. After th...
