Abstract
Chitosan was used as a stabilizer to synthesize chitosan cobalt(II) [Chit–Co(II)] and its zerovalentcobalt nanobiocomposite via chemical reduction. The complex and Chit–ZVCo were used to polymerize vinylacetate in aqueous Na2SO3. The Chit–Co(II) and Chit–ZVCo were characterized by spectroscopic (FT-IR and UV–Visible), XRD and SEM techniques. Application of these biomaterials for the polymerization of VAc afforded polyvinylacetate with improved yield. Comparing the reactivity of Chit–Co(II) and Chit–ZVCo, it was evident that Chit–ZVCo performed as better heterogeneous catalyst based on the synergic effect of interaction of cobalt nanoparticles and chitosan at the nanometric scale.
