Abstract:
Cross-linked thermosets are investigated by 13C solid-state nuclear magnetic resonance (NMR) spectroscopy to determine their structure and to distinguish important epoxy resins and hardening agents. In addition to the epoxy resin and hardening agent, the identification of phosphorus-containing flame retardants is demonstrated by 31P solid-state NMR. These studies provide a spectral database for routine use, which is finally applied to analyze commercial products containing an unknown multicomponent system.

Chemical Shift: Internal References and Solvent Effects
The internal reference compound generally used in NMR spectroscopy is tetramethylsilane (TMS). TMS is preferred because it is chemically inert, soluble in NMR solvents, and easily removable. Also, the highly shielded methyl protons in TMS yield an intense...
