Synthèse de monomères éthyléniques issus de la biomasse végétale précurseurs de biopolymères

Written by sctunisie no comments

New ethylenic monomers based on 1,4:3,6-dianhydrohexitols and 5-bromo-2-furaldehyde were prepared by a metal free synthesis of furannyl-isosorbide and isomannide derivatives. The monomers were obtained with high yields. The polymerization of the unsaturated monomer using 2,2’-azobisisobutyronitrile as catalyst provides the resulting polymethacrylate benzyl isosorbide with high molecular weight. The bio-based monomers and polymer were charactherized by several analitycal methods such as 1H NMR, 13C NMR and FTIR spectroscopy. Thermal properties of the polymer were investigated by means of differential scanning calorimetry (DSC) and molecular weights by SEC measurements.
