摘要：

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.
