| Abstract: | The synthesis and characterization of 2-formamido-2-methylpropyl acrylate (FMPA) is reported. 13C NMR spectra of FMPA in CDCl3, CD3OD, DMSO-d6, DMF-d7, and D2O exhibit two pairs of lines for all seven carbon atoms at room temperature; the ratio of the two conformers varies moderately with solvent (21 : 79 to 41 : 59). The conformers are believed to involve strong internal hydrogen bonding which is not completely broken even by the addition of trifluoroacetic acid to CDCl3 (1/1, v/v). However, the pairs of lines coalesce in turn as the temperature is raised to 120°C in DMSO-d6. FMPA was polymerized at 35°C in DMF and CHCl3, using a free radical initiator and the polymer was characterized by 13C NMR spectroscopy. |
