Telomerization of butadiene with starch in water: role of the surfactants
Résumé
Nowadays, the preparation of bio-based polymers remains a challenging issue. The modification of starch by hydrophobic chemical substitutions results in an innovative material. We introduced the hydrophobic part of the derivative via catalytic butadiene telomerization using exclusively water as solvent in the presence of surfactants. In this paper, we describe the influence of the nature of the surfactant on the reaction, CTAB (cetyltrimethylammonium bromide) giving the best reactivity. Moreover, some physicochemical properties of modified starches are evaluated showing their hydrophobic behaviours.
