Chemical shift effects in nuclear magnetic resonance imaging (NMRI) of adhesives are demonstrated and discussed. The effects of more than one proton resonance on slice selection and on the final image are shown. Relative chemical shift effects are introduced to explain, numerically, how sample size, spectral width, and gradient strengths affect the observed image. The potential and limitations of using chemical shift effects in adhesive studies are discussed with illustrative examples. A model adhesive system was studied which was a typical solventless two-component polyurethane adhesive.

ABSTRACTSilicone based biomaterials are characterized with NMR. Bulk spin-lattice (T1) and spin-spin (T2) relaxation times are measured in polydimethylsiloxane (PDMS) model networks and various types of implants. The T2 results seem to indicate that crosslink densities of these biomaterials are lower than those of the PDMS model networks studied. 1H chemical shift NMR imaging techniques are developed to investigate the aging (e.g., migration of free polymer, rupture due to mechanical stress, etc.) of biomaterials in vivo.
