130. Preparation, Morphology, and Biolabeling of Fluorescent Nanoparticles Based on Conjugated Polymers by Emulsion Polymerization.
Novel nanoparticles based on conjugated polymer with good fluorescent properties were synthesized by Suzuki coupling reaction using certain surfactants as one kind of special emulsion polymerization. The luminescent properties of the prepared nanoparticles could be controlled by selecting different monomers. Without using substances comprising any heavy metal element, these fluorescent nanoparticl...

Synthesis and Characterization of Biodegradable Crosslinked Polymers from 5-Hydroxylevulinic Acid and α,ω-Diols
Novel biodegradable chemically cross-linked polymers, poly(5-hydroxylevulinic acid-co- , -diol)sax (PHLA-diols), were synthesized from 5-hydroxylevulinic acid and α,ω, -diols and characterized by Fourier transformax infrared spectroscopy, differential scanning calorimetry, thermogravimetric analysis, and dynamic mechanical analysis. The gel content, swelling ratio, tensile properties,...

Thermoresponsive dendronized polymers with tunable lower critical solution temperatures
A series of first (PG1) and second generation (PG2) dendronized polymers were synthesized which exhibit fast and sharp phase transitions with negligible hystereses in aqueous solutions and apparent lower critical solution temperatures (LCSTs) in the range of 33–49 oC.

Tuning Polymer Thickness: Synthesis and Scaling Theory of Homologous Series of Dendronized Polymers
The thickness of dendronized polymers can be tuned by varying their generation g and the dendron functionality X. Systematic studies of this effect require (i) synthetic ability to produce large samples of high quality polymers with systematic variation of g, X and of the backbone polymerization degree N, (ii) a theoretical model relating the solvent swollen polymer diameter, r, and persistence le...

Synthesis and photoluminescence stability of non-conjugated polymers based on fluorene and benzoxazole
A kind of non-conjugated blue luminescent polymer based on fluorene and benzoxazole was synthesized via solution condensation polymerization from 2,2-bis(3-amino-4-hydroxyphenyl)-propane and 2,7-dicarboxyl-9,9-dioctyl-fluorene and was characterized with H NMR, FT-IR, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), UV–vis absorption and photoluminescence (PL) ...

Synthesis and characterization of new precursor polymers of poly[2-methoxy-5-(4-bromobutoxy)phenylene vinylene
Two kinds of novel water soluble polyelectrolyte and organic soluble precursor polymers of poly(phenylene vinylene) with bromine substituted side chain were synthesized from tri-sulfonium salt monomer. The results showed that the sulfonium salt on the butoxy substituted side chain did not take part in the polymerization, thus the organic soluble precursor can be obtained at proper condition. Prima...

Rapid and reversible hydrogen storage in clathrate hydrates using emulsion-templated polymers
A method for greatly accelerating the storage of gases such as hydrogen in clathrates by supporting the clathrate phase on a highly macroporous emulsion-templated polymer is presented. The gravimetric penalty is low due to the low bulk d. of the support, no mech. mixing is required, and the system is fully recyclable over multiple charge/discharge cycles.

Computer simulation of conic-shaped patterns on fracture surfaces of polymers
Fractographic analysis, using scanning electron microscopy, is an important method to study polymer fracture behavior. There are several distinctive patterns on
fracture surfaces, such as radial striations, regularly spaced ‘rib’ markings, and conic-shaped patterns. The conic-shaped pattern is the intersection locus of a moving planar crack front and a radially growing circular craze ...
