Botana et al. [50] have prepared polymer nanocomposites, based on a bacterial biodegradable thermoplastic polyester, PHB and two commercial montmorillonites [MMT], unmodified and modified by melt-blending technique at 165°C. PHB/Na and PHB/ C30B were characterized by differential scanning calorimetry [DSC], polarized optical microscopy [POM], X-ray diffraction [XRD], transmission electron microscopy [TEM], mechanical properties, and burning behavior. Intercalation/exfoliation observed by TEM and XRD was more pronounced for PHB30B than PHB/Na,... 

Nanocomposites of organomodified montmorillonites (C20A, C25A, and C30B) and a biodegradable PEA were obtained by in-situ polycondensation of sodium chloroacetylaminohexanoate [75]. This synthesis was based on a thermal polycondensation reaction in which the formation of a metal halide salt became the driving force of the process [76, 77]. 

Naguib et al. synthesized biodegradable poly(ester-urethane) nanocomposites based on PHB and (PHB/PCL-PEG-PCL) [66] reinforced with grafted montmorillonite (Mt-PCL) [87] and Cloisite 30B (C30B) [20]. They reported that thermal stability of poly(ester-urethane)s was enhanced with increasing the filler content (Table 7.1).
