Liquid state NMR studies of polymer dynamics and conformation,available from spin-spin (.) couplings. This is because the size of three-bond and longer range spin-spin couplings depends on the dihedral angles between the bonds to the nuclei under observation. NOEs between vicial protons depend on local dihedral angles in a similar way.SIT 发表于 2025-3-27 21:06:43

High resolution solid-state NMR studies of polymer chemical and physical structures,d 4). Even rubbery, crosslinked polymers, which are completely prevented from flowing by their three-dimensional network structures, produce high-resolution spectra under these same conditions. These observations are the direct consequence of rapid, isotropic motions of the polymer segments.CEDE 发表于 2025-3-28 05:23:32
Solution-state NMR determination of polymer end-groups, substituents and minor structures, be able to correlate the properties of polymeric materials with their structures and the methods of preparation, but also to understand all the reactions involved in a polymerization. With sufficient knowledge, it may be possible to select conditions for polymerization so that undesirable groupings can be reduced in number or even eliminated.deciduous 发表于 2025-3-28 07:10:47
