Résumé

Introduction Materials with strong environmental impact are still used in disposable products such as food packaging materials. Alternative materials bio-sourced or biodegradable are highly desirable. Polyhydroxyalkanoates (PHAs), obtained from microbial fermentation, meet the two qualities by being bio-based and biodegradable but show a lack of properties showing a relatively high stiffness and brittleness while showing a relatively high glass transition temperature (0-5°C) compared to its counterpart low density polyethylene 2 . A conventional strategy to improve thermomechanical properties of the polymer consists in blending the brittle material with a ductile material. We report the results of blending PHBV with poly(butylene succinate-co-adipate) (PBSA) by melting state at different PHBV/PBSA content weight ratio. PBSA is a biodegradable aliphatic polyester, showing a low melting temperature, good thermal stability and low glass transition temperature (-45°C).
