Résumé

Due to depletion of fossil resources and global environmental respect awareness, interest in biobased plastic materials is tremendously growing. Direct extraction of vegetal polymers like cellulose followed by a chemical modification to bring new properties is one of the paths to produce a bioplastic. Progressively replaced by oil-based polymers in the sixties, thermoplastic cellulose esters are now reconsidered for various materials applications. To improve mechanical weaknesses of cellulose esters based materials, the technique of blending has been widely used. Various blending candidates of cellulose esters have been studied, but mostly with the goal to make the material biodegradable. For this purpose Polyestercarbonates, Polylactides and Polyhydroxyalcanoates were used. To our knowledge, small interest has been paid on durable cellulose ester based blends. More particularly, only few studies have considered the good mechanical properties of cost-effective and easy-available polyolefins as blending partners of cellulose esters.
