The composites formed by sugarcane bagasse and thermoplastic polymers, such as polypropylene (PP), polyethylene (PE), and ethylene‐ co ‐vinyl acetate (EVA), have been analysed by carbon‐13 high‐resolution solid‐state nuclear magnetic resonance (NMR), employing crosspolarization magic angle spinning (CPMAS); variable contact‐time experiment and proton spin‐lattice relaxation time in the rotating frame. NMR responses showed that these techniques can be used to observe the degree of compatibility and homogeneity of different polymers composites. © 2001 John Wiley & Sons, Inc.
