“…PBS has been employed as homopolymer with or without the use of isocyanates, [44,49,50,52,54,55,63,64,76,83,85,89,94,98] as a blend with PLA, [59,91] poly(L-lysine), [69] poly(3hydroxybotyrate-co-valerate), [81] PCL [95] or in copolymeric systems.…”

“…[73] Blending of PBS with polylysine led to a worsening of the mechanical properties, especially for polylysine amounts higher than 20%; this has been correlated to the phase separation between the two domains. [69] The addition of organic or inorganic fillers had a significant impact on the PBS properties. In general, elastic modulus and elongation to break respectively increased and decreased with the increasing filler content as due to the composite enhanced stiffness, [83] while no general trend can be observed for tensile strength.…”

“…In addition, the mechanical and thermal properties of the PBS depend on the degree of crystallinity and the spherulite morphology . Degradability of the PBS has been widely studied under different environmental conditions . These studies claimed that the PBS is susceptible to hydrolysis in the presence of moisture/water.…”

In this study, the durability of poly(butylene succinate) (PBS), poly(butylene adipate-co-terephthalate) (PBAT), and PBS/ PBAT blend was assessed by exposure to 50 C and 90% relative humidity for a duration of up to 30 days. Due to the easy hydrolysis of esters, the mechanical properties of PBS and PBAT were significantly affected with increasing conditioning time. The PBS, PBAT, and PBS/PBAT showed an increase in modulus as well as a decrease in tensile strength and elongation at break with increased exposure time. Furthermore, the impact strength of PBAT remains unaffected up to 30 days of exposure. However, it was clearly observed that the fracture mode of PBS/PBAT changed from ductile to brittle after being exposed to high heat and humid conditions. This may be attributed to the hydrolysis products of PBS accelerating the degradation of PBAT in the PBS/PBAT blend. The differential scanning calorimetry results suggested that the crystallinity of the samples increased after being exposed to elevated temperature and humidity. This phenomenon was attributed to the induced crystallization from low molecular weight polymer chains that occurred during hydrolysis. Therefore, low molecular weight polymer chains are often favored to the crystallinity enhancement. The increase in crystallinity eventually increased the modulus of the conditioned samples. The enhanced crystallinity was further confirmed by polarizing optical microscopy analysis. Moreover, the hydrolysis of the polyesters was evaluated by scanning electron microscopy, rheology, and Fourier transform infrared spectroscopy analysis.
