Characterization of Natural Rubber from Manicoba (Manihot glaziovii): Microstructure and average molecular weight
Material type:
TextPublication details: Journal of Natural Rubber Research 1991Description: 134-136Subject(s): Summary: The microstructure and average molecular weight of Manihot glaziovii rubber, are presented. the natural rubber constitutes mainly of cis-1,4-isoprene units and shows Mv values ranging from 1.0 x 10 raised to 6 and 1.5 x 10 raised to 6. Mn and Mw were found to be 1.1 x 10 raised to 6 and 2.0 x 10 raisedto 6, respectively, with a polydispersity of 1.3. The structural determination was based on infra-red (ir), 1H and 13C NMR. The average molecular weights were obtained from viscosity experiments and GPC.
