High solid content poly (styrene-co-butyl acrylate) latex ( with 20% and 40% solid content) including high amounts of Cloisite 30B (7 wt% and 10 wt%) were kinetically investigated. Gravimetric method via measuring the rate of polymerization, number of particles and average number of radicals per particle was used. Results showed that by increasing the solid content; the average diameter of poly...

Highly heat and oxidation-resistant materials prepared using the silicon-containing thermosetting polymer, poly[(phenylsilylene)ethynylene-1,3-phenyleneethynylene] [-Si(Ph)(H)-C C-C6H4-C C-] are summarized. This polymer is light, moldable, soluble in solvent, and highly heat resistant. It is prepared by the dehydrogenative cross-coupling reaction of the Si-H bond of phenylsilane and the C-H bon...

A novel cell-targeting, pH-sensitive polymeric carrier was employed in this study for delivery of the anticancer drug bortezomib (BTZ) to cancer cells. Our strategy is based on facile conjugation of BTZ to catechol-containing polymeric carriers that are designed to be taken up selectively by cancer cells through cell surface receptor-mediated mechanisms. The polymer used as a building block in ...

An Eu(III)-containing polymer can exhibit intense induced circularly polarized luminescence (CPL) in the presence of proline. In addition, the optical anisotropy factor (g(lum)) of the polymer for (5)D0 → (7)F1/(7)F2 transition was much higher than that of a single model molecule, which reveals the amplification effect of CPL arising from the conjugated polymer structure.

A thin-film transistor: An n-type polymer semiconductor, poly(2,3-bis(perfluorohexyl)thieno[3,4-b]pyrazine), was synthesized through a Pd-catalyzed polycondensation employing a perfluorinated multiphase solvent system. This is the first example of an n-type polymer semiconductor with exclusive solubility in fluorinated solvents. The fabrication of organic field effect transistors containing thi...

A Zn–Ni alloy was electrodeposited on a Cu electrode at current density of 10–5000 A·m−2, charge 5 × 104 C·m−2, and temperature 293 K in an unagitated zincate solution containing the reaction product epichlorohydrin imidazole (EI polymer) as brightener. The effect EI polymer deposition behavior investigated. transition densities which shifted from normal type to anomalous were 50–100 A·m−2 10–2...

Photoluminescent energy transfer was investigated in conjugated polymer-fluorophore blended thin films. A pentiptycene-containing poly(phenyleneethynylene) was used as the energy donor, and 13 fluorophores were used as energy acceptors. The efficiency of energy transfer was measured by monitoring both the quenching of the polymer emission Page 1 of 57 ScholarOne, 375 Greenbrier Drive, Charlotte...

a series of sorbents containing various amounts of borate groups were prepared by chemical immobilization ofp-aminoethylphenylboric acid on a copolymer- treated organosilane spacer glass plates. it was found thatbaker's yeast cells selectively adhered to these supports. yeast cells stained with procion red he-3b formeddenser and more stable layer on the copolymer-grafted supports compared onto ...
