反气相色谱法测定苯-丙-硅共聚物的溶解性能

本文应用反气相色谱法测定了苯乙烯-丙烯酸丁酯-乙烯基三乙氧基硅氧烷共聚物与探针分子的表观热力学相互作用参数X12,并以此研究了聚合物与小分子有机化合物的溶解性能。实验中测定了探针分子在聚合物固定相中的保留时间,计算出比保留体积Vg°及X12。根据聚合物与探针分子相溶性判定原则:当X12(0.5时,该探针分子为聚合物的良溶剂,X12越小,溶剂的溶解能力越强;当X12(0.5时,该探针分子则为聚合物的不良溶剂;当X12=0.5时,则该探针分子为聚合物的理想溶剂。预估了聚合物与小分子有机化合探针分子的溶解性能,为该聚合物作为固相微萃取吸附剂的应用性能研究提供了重要的依据。

Synthesis and fluorescence properties of star‐shaped polymers carrying two fluorescent moieties

A well‐defined fluorescent star‐shaped polymer containing two different fluorescent functionalities one in the main chain and another in the end group was designed and synthesized by combining atom transfer radical polymerization (ATRP) and azide‐alkyne click reaction. The star polymer with four arms was prepared from copolymerization of methyl methacrylate and 4‐(2‐(9‐anthryl))‐vinyl‐styrene using ATRP. Subsequently the end group was modified with another fluorescent moiety by click coupling. The structure of all the intermediate and final products was established through NMR spectroscopy, Fourier transform infrared spectroscopy, gel permeation chromatography, UV?visible spectroscopy and fluorescence spectroscopy. The novel hybrid polymer exhibits an attractive high fluorescence at 494 nm and over a broad range which was a combination of both the fluorescence moieties. © 2013 Society of Chemical Industry     

Polymer precursor to diamondlike carbon prepared by the polymerization of α,α,α‐trichlorotoluene and acetonitrile

A novel liquid/solid two‐phase reaction of α,α,α‐trichlorotoluene (PhCCl₃) and acetonitrile (AN) has been discovered that produces a carbon‐based polymer with diamondlike structure at the atomic level. The solid phase is potassium hydroxide particles, and the liquid phase is a tetrahydrofuran solution of PhCCl₃ and AN containing a certain amount of tetrabutylammonium bromide as a phase‐transfer catalyst. The structure of the carbon‐based polymer has been characterized by elemental analysis, Fourier transform infrared spectroscopy, and ¹H‐ and ¹³C‐NMR spectroscopy. The pyrolysis of the carbon‐based polymer at 800°C under a nitrogen atmosphere leads to the formation of a diamondlike carbonaceous material according to the results of X‐ray photoelectron spectroscopy and Raman spectroscopy. © 2003 Wiley Periodicals, Inc.

Synthesis,X-ray structure,and polymerization of 1-vinyl-3-cyanomethylimidazolium chloride

A new monomer, 1-vinyl-3-cyanomethylimidazolium chloride (1), was synthesized via quaternization of 1-vinylimidazole with chloroacetonitrile. The monomer was characterized using ¹H– and ¹³C–NMR as well as Raman spectroscopic techniques; its crystal structure was studied by means of X-ray analysis. The radical polymerization of 1 in aqueous solution brought about the formation of a polyelectrolyte that retains cyano groups intact and possesses film-forming properties. The structure of the polymer was characterized by NMR and Raman spectroscopy. The high viscosity of aqueous solutions and chemical structure of the polymer obtained suggest its possible applications as a thickener and/or detergent additive. © 2001 John Wiley & Sons, Inc.

Preparation of ultra-high temperature SiC–TiB2 nanocomposites from a single-source polymer precursor

SiC–TiB₂ ceramic nanocomposites are valuable ultra-high temperature materials, which are rarely prepared from preceramic polymers. In this work, we synthesized SiC–TiB₂ nanocomposites from a new preceramic polymer called titanium- and boron-modified polycarbosilane (TB–PCS). The polymer structure was characterized by Fourier transform infrared spectroscopy (FT-IR) and nuclear magnetic resonance (NMR) spectroscopy. The structure, composition, and morphology of the resulting ceramic products were investigated by FT-IR, X-ray diffraction, and transmission electron microscopy. The elements of titanium and boron were incorporated into the preceramic polymer, and nanoscale TiB₂ and β-SiC grains generated in situ were detected in the pyrolyzed ceramic products at temperatures higher than 1400 °C. The new preceramic polymer presents a novel approach to preparing SiC–TiB₂ nanocomposites.     

Characterization and comparison of Asian lacquer saps

Five kinds of Asian lacquer saps, Thailand raw and kurome, China raw and kurome, and Vietnam raw lacquer, were characterized by IR, UV resistance, viscosity, rigid-body pendulum physical property-testing and NMR measurements. The results showed that although Thailand lacquer has the highest oligomer and polymer content, its drying speed is the slowest, and it has the best UV resistance. In addition, the monomer, dimer, trimer, and tetramer fractions of thitsiol of Thailand raw lacquer were separated by HPLC and analyzed by NMR spectroscopy. Almost all proton and carbon NMR peaks were assigned, and the structure of thitsiol was confirmed.     

Synthesis and characterization of a novel terephthalate‐bridged ladderlike polymethylsiloxane

A novel soluble terephthalate‐bridged ladderlike polymethylsiloxane was synthesized successfully by stepwise coupling polymerization in three steps, including hydrosilylation coupling, hydrolysis and polycondensation. The bis(3‐methyldichlorosilylpropyl) terephthalate monomer was first synthesized by hydrosilylation reaction in the presence of dicyclopentadienylplatinum(II) chloride (Cp₂PtCl₂) catalyst. The structures of the monomer and the polymer were characterized by FTIR, ¹H NMR, ¹³C NMR and ²⁹Si NMR spectroscopy, mass spectrometry, X‐ray diffraction, differential scanning calorimetry, vapour pressure osmometry and gel permeation chromatography. Characterization data indicate that the synthesized polymer possesses an ordered ladderlike structure. © 2000 Society of Chemical Industry     

Synthesis of poly(ε-caprolactone)-based polyurethane semi-interpenetrating polymer networks as scaffolds for skin tissue regeneration

A new biodegradable poly(ε-caprolactone)-polyurethane semi-interpenetrating polymer network (PCL-PU-semi-IPNs) was synthesized through the reaction of hydroxyl-terminated four-armed star-shaped PCL, 1,4-diisocyanatobutane, and ethylenediamine. Afterwards, the three-dimensional (3D) porous structure of the polymer was prepared through particulate leaching and freeze-drying methods. The chemical structure of star-shaped block PCL-PU polymer was confirmed by ¹H NMR and IR spectroscopy. The morphology of the fabricated PCL-PU-semi IPN scaffolds was identified by scanning electron microscopy. Results indicated that lower polymer concentration can lead to formation of an isolated pore with a small size, while increasing polymer concentration increases the pore size. Fibroblast cells culturing on the scaffold suggests that the fabricated PU-based scaffold is biocompatible and can be considered as a suitable scaffold material for skin tissue engineering applications.
