Abstract
This work describes the synthesis and physicochemical and microstructural characterization of poly(sorbitol adipate co-citrate) with the aim of obtaining a sustainable biopolymer derived from renewable and non-toxic sources intended for applications such as biomaterial. Polymerizations at three different ratios of sorbitol and adipic and citric acids (A, B and C) were studied. The materials were characterized by X-ray diffraction (XRD), infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) techniques. Such analyses showed that only in state C was an amorphous copolyester obtained, with different particle sizes and visibly hard and with a translucent yellowish color.
