Resumen:
Chemical modification of chitosan, specially grafting with different polymers is animportant strategy in the production of bio-based materials with enhanced properties. In the presentstudy, chitosan was grafted with n-butyl acrylate, in a surfactant-free emulsion polymerization.Stable dispersions with high grafting efficiency were obtained and the microstructure of the castedfilms was analyzed by positron annihilation lifetime spectroscopy and small angle X-ray scattering.Results are discussed in terms of the number and distribution of the grafting sites.
