Gc. Stael et al., C-13 HIGH-RESOLUTION SOLID-STATE NMR-STUDY OF NATURAL FIBERS OBTAINEDFROM SUGAR-CANE WITHOUT TREATMENT AND THEIR COMPOSITES WITH EVA, Polymer testing, 17(3), 1998, pp. 147-152
Natural fibres from three distinct type of sugar cane without any spec
ific treatment to remove the sugar, lignin and impurities and their co
mposites with EVA, have been analysed by carbon-13 high-resolution sol
id state nuclear magnetic resonance (NMR). The NMR techniques used wer
e cross-polarization magic angle spinning (CP/MAS); variable contact-t
ime and proton spin-lattice relaxation time in the rotating frame (T(1
)(H)rho). From those measurements it was observed that the molecular m
obility of chains along the fibres has a particular behaviour. (C) 199
