NMR Spectroscopy of Polymers
نویسنده
چکیده
molecular tumbling causes that anisotropy of nuclear interaction now plays dominant role in the appearance of NMR spectra. Frankly speaking the NMR signals are very broad and spectra become featureless. In general missing isotropic tumbling leads to severe broadening of the detected signals. The lack of resolution, however; does not mean the absence of structure information, it rather reflects its overcrowding in such extent that we are not able to read out and understand it. Due to this fact various techniques have been proposed to increase spectral resolution. UNESCO/IUPAC Course 2005/2006

Synthesis of some network polymers with siloxane units as a drug delivery system
New biodegradable network polymers containing siloxane-linked polymeric prodrugs of 5-ammino-2-hydroxybenzoic acid (5-ASA) in the main chain were prepared by ter polymerization of methacrylic acid (MA), 2-hydroxyethylmethacrylate (HEMA), and bis (trimethylsilyloxy) methylsilane (VBM) in the presence of some new cross-linking agents.The monomers and polymers were characterized by FT-IR and 1H-NM...
متن کاملNMR Studies on the Properties of Polymers in Supercritical CO2
Using NMR spectroscopy and NMR imaging, the behaviour of polymers in supercritical CO2 (sc-CO2) using a custom-made cell designed from poly(ether ether ketone) (PEEK) has been observed. The mechanism of swelling of polymers in sc-CO2 and the overall effects of sc-CO2 on the transport properties of both small and large molecules has been studied. We report on the swelling characteristics of radi...
متن کاملNuclear Magnetic Resonance Spectroscopy in Macromolecular Science
Today, virtually every experimental paper published in ‘‘Macromolecular Chemistry and Physics’’ includes characterization of the polymers under study by nuclear magnetic resonance (NMR) spectroscopy. In addition to monitoring the various synthetic steps, which eventually lead to the new polymers or supramolecular systems described, high-resolution NMR provides a number of important parameters, ...
متن کاملSynthesis of new polyurethanes based on 5, 6, 7, 8 – tetrabromo – 2, 3 – dihydro – 1, 4 – phthalazine dione
In this work, 5,6,7,8-Tetrabromo-2,3-dihydro-2,3-bis(2-hydroxyethyl)phthalazine-1,4-dione is synthesized by the reaction of 5,6,7,8-tetrabromo-2,3-dihydrophthalazine-1,4-dione with 2-bromoethanol in the presence of triethylamine. The obtained monomer was polymerized with different diisocyanates, including hexamethylenediisocyanate (HMDI), tolylene-2,4-diisocyanate (TDI), isophoronediisocyanate ...

متن کاملSolid state NMR studies of gels derived from low molecular mass gelators
Since its invention more than six decades ago, nuclear magnetic resonance (NMR) spectroscopy has evolved as an inevitable part of chemical as well as structural analysis of small molecules, polymers, biomaterials and hybrid materials. In the solution state, due to the increased viscosity of complex viscoelastic fluids such as gels, liquid crystals and other soft materials, the rate of molecular...
