Etude microstructurale et modification des propriétés du poly butylène succinate (PBS), un polyester aliphatique.

Abstract

Poly (butylene succinate) (PBS) is a polyester known for a long time but which regains interest thanks to its biosourced and biodegradable potential as well as its mechanical properties close to those of polyolefins. However, its rigidity is still too low and its high sensitivity to hydrolysis limits its use over time, even under standard conditions of temperature and humidity. Improvements in the stability of PBS are possible and several solutions have been considered. Interest will be focused on modifying the rigidity of PBS by adding natural fibers to improve the mechanical and physical properties. The addition of fillers in the material may also be effective in neutralizing the ends of acid chains catalyzing degradation, using calcium carbonate, or in limiting the permeability of the material, by incorporation of montmorillonite (MMT).
