“…Our group has recently studied isodimorphism in several random copolymer systems [ 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. Isodimorphic crystallization has recently been found in different types of random copolymers such as poly (decamethylene succinate- ran -decamethylene fumarate), poly (butylene succinate-co-cis-butene succinate) and poly (hexamethylene carbonate)-co-poly (hexamethylene urethane) [ 30 , 31 , 32 , 33 , 34 , 35 ].…”

Isodimorphic behavior is determined by partial inclusion of comonomer segments within the crystalline structure and arises from the comparatively similar repeating chain units of the parental homopolymers. Isodimorphic random copolymers are able to crystallize irrespective of their composition and exhibit a pseudo-eutectic behavior when their melting point values are plotted as a function of comonomer content. At the pseudo-eutectic point or region, two crystalline phases can coexist. On the right-hand and the left-hand side of the pseudo-eutectic point or region, only one single crystalline phase can form which is very similar to the crystalline structures of the parent homopolymers. This article aims to study the synthesis method, structure, crystallization behavior and mechanical properties of isodimorphic random PBS-ran-PCL copolyesters. Moreover, this study provides a comprehensive analysis of our main recent results on PBS-ran-PCL random copolyesters with three different molecular weights. The results show that the comonomer composition and crystallization conditions are the major factors responsible for the crystalline morphology, crystallization kinetics and mechanical performance of isodimorphic random copolyesters. Our studies demonstrate that in the pseudo-eutectic region, where both crystalline phases can coexist, the crystallization conditions determine the crystalline phase or phases of the copolymer. The relationships between the comonomer composition and mechanical properties are also addressed in this work.

“…This provides a high melting point to the PBS and a more stabilized crystalline structure than other copolyesters. In general, those polymers that can form isodimorphic copolymers with PBS are characterized by a strong crystallization ability [63]. Thus, the PBS-based copolymers display a pseudoeutectic point or region around 50%, as the PBS-ran-PBAz [57][58][59][60], PBS-ran-PBA [48,51], and PBS-ran-PCL [26,46,47,56,61] studied by our group and shown in Figure 3.…”

“…The determination of the position of the pseudo-eutectic point is still unclear; however, it seems that it depends on the crystallization ability of the material [62][63][64]. The PBS possesses a symmetrical chemical structure, adopting an all-trans conformation within its unit cell, facilitating the formation of a highly ordered crystalline structure [63]. This provides a high melting point to the PBS Figure 3 shows that, typically, the PBS-based copolymers display an isodimorphic behavior, exhibiting a clear pseudo-eutectic point.…”

A Review on Current Strategies for the Modulation of Thermomechanical, Barrier, and Biodegradation Properties of Poly (Butylene Succinate) (PBS) and Its Random Copolymers

et al. 2022

The impact of plastics on the environment can be mitigated by employing biobased and/or biodegradable materials (i.e., bioplastics) instead of the traditional “commodities”. In this context, poly (butylene succinate) (PBS) emerges as one of the most promising alternatives due to its good mechanical, thermal, and barrier properties, making it suitable for use in a wide range of applications. Still, the PBS has some drawbacks, such as its high crystallinity, which must be overcome to position it as a real and viable alternative to “commodities”. This contribution covers the actual state-of-the-art of the PBS through different sections. The first section reviews the different synthesis routes, providing a complete picture regarding the obtained molecular weights and the greener alternatives. Afterward, we examine how different strategies such as random copolymerization and the incorporation of fillers can effectively modulate PBS properties to satisfy the needs for different applications. The impact of these strategies is evaluated in the crystallization behavior, crystallinity, mechanical and barrier properties, and biodegradation. The biodegradation is carefully analyzed, highlighting the wide variety of methodologies existing in the literature to measure PBS degradation through different routes (hydrolytic, enzymatic, and soil).
