Kinetics of solid-state NMR cross-polarization from protons to carbon-13 in surgical sutures.
Commercial Dexon surgical sutures, made of polyglycolide (PGA), were examined using (13)C CP/MAS NMR. The study shows that detailed analysis of the cross-polarization (CP) process is useful in the peak assignments and in the assessment of molecular mobility in the polymer domains. Crystallinity of PGA in the sutures was estimated at ca. 55%.
