Synthesis and Characterization of Chitosan-PHB Blends

Blends of chitosan, [poly( ß-1,4)-2-amino-2-deoxy-D-glucopyranose], CH, the desacetylated product of chitin, with poly(3-hydroxybutyrate), PHB, usingratios of 90/10, 75/25, 50/50, 25/75, and 10/90 of chitosan-PHB were obtained. The blends were obtained using trifluoracetic acid as co-solvent under c...
