19.  Thermal Analysis of the Compounds Obtained by Polymerization Between Inulin Esters And Different Monomers

Authors: G. Rusu, L. Rusnac, G. Bandur, I. Manoviciu, N. Joly, P. Martin


Abstract:

Inulin was esterified with methacryloyl chloride and palmytoyl chloride in order to transform the polysaccharide into a possible biodegradable plastic. The obtained inulin esters were, further, copolymerized with n–butyl acrylate and 2–ethyl hexyl acrylate. The FT-IR spectroscopy was used to characterize the inulin esters and the obtained copolymers. The glass transition temperature was evaluated using DSC and DMA technique. Furthermore, using DMA the storage and loss modulus was evaluated. Thermogravimetrical studies were carried out on the plastics and the thermal stability of the obtained products was studied. These new modified polysaccharides would have biodegradability properties.


Keywords: inulin, inulin copolymers, FT-IR spectroscopy, glass temperature
