Summary: PBS and PBSA were irradiated with gamma radiation up to a dose of 400 kGy, resulting in the formation of gel content. PBSA exhibited higher gel content compared to PBS. Analysis revealed that chain scission predominated over crosslinking. Branching and chain scission increased the dispersity and affected the molecular weight. NMR analysis showed the appearance of new species and changes in species with increasing dose. The thermal properties, especially crystallization temperature, were significantly affected by irradiation. Mechanical properties of both polymers were greatly reduced, making them fragile even at low doses.

Summary: The development of biodegradable and compostable materials, such as polybutylene succinate (PBS), as alternatives to fossil-based plastics is highly important. PBS is a compostable aliphatic polyester with good mechanical strength and thermal resistance. However, it is often blended with other polymers, fillers, and additives to improve processability and mechanical performance. Recent advances in polymer blending processes have made PBS blends an interesting material platform for applications requiring a balance of mechanical strength, flexibility, thermal resistance, and compostability.

Summary: Nylon fishing nets cause damage to marine environments when lost, so a biodegradable poly(butylene succinate) (PBS) resin was developed. By adding adipic acid and ethylene glycol to PBS, poly(butylene adipate-co-butylene succinate-co-ethylene adipate-co-ethylene succinate) (PBEAS) resin with excellent properties and low melting point was synthesized. This resin can be used for gill nets, expanding the application of biodegradable fishing gear.

Summary: This study explores the possibility of blending PBS and PCL with BSxCLy copolymers and systematically studies the crystallization behavior of the blends. The results show that the PBS/BS78CL22 blend exhibits good miscibility at high PBS content, while the PCL/BS15CL85 blend still displays partial miscibility at high PCL content. The BS46CL54 copolymer can crystallize in both PBS and PCL type crystals, depending on the polymeric matrix.

Summary: Polymeric materials have a wide range of applications due to their controllable properties. In this study, a series of PBS-DLS-PEG copolymers were synthesized with different molecular weights of PEG to investigate their surface and thermal properties. The incorporation of higher molecular weight PEG improved the surface wettability of the materials while maintaining their thermal properties.

Summary: This study investigated the effects of poly(butylene-succinate) (PBS) and cassava pulp (CP) at different particle sizes on the properties of PBS/CP biocomposites. The results showed that the addition of CP improved the hardness and Young's modulus of the biocomposites, but decreased their tensile strength and impact strength. The use of CP with a particle size of 250 μm resulted in better particle dispersion and compatibility. A CP content of 40% showed the best biodegradability.

Summary: Novel biobased and biodegradable PBS-b-PBSe multiblock copolymers were successfully synthesized with high thermal stability. The two blocks crystallized separately in both amorphous and crystalline phases. The mechanical properties of the copolymers were significantly improved compared to homopolymers.

Summary: PLLA and PBS are biodegradable, compostable, and biocompatible polymers that have complementary properties, making blending them an opportunity to exploit their favorable characteristics. However, research on the properties of PLLA/PBS blends has yielded contradictory results, creating complexity in their utilization.

Summary: Biodegradable polymers, such as poly(butylene succinate) (PBSu) biocomposites, containing biochar (BC) filler can improve mechanical properties, thermal transitions, and biodegradability. The addition of BC enhances tensile and impact strengths, facilitates crystallization, and increases thermal diffusivity and conductivity. However, it also causes an increase in overall dielectric permittivity. Furthermore, the enzymatic hydrolysis degradation rate of biocomposites is found to increase with increasing BC content.

Summary: Triboelectric nanogenerator (TENG) devices are simple and efficient systems for converting mechanical energy into electricity. However, the lack of attention to recycling or reusing TENG devices, which are mostly made of non-biodegradable polymers, leads to negative environmental impacts. Developing biodegradable triboelectric materials is crucial for sustainable use and disposal of TENG devices.

Summary: The impact of plastics on the environment can be reduced by using biobased and/or biodegradable materials as alternatives. One promising alternative is poly (butylene succinate) (PBS) due to its favorable properties. However, the high crystallinity of PBS poses challenges. This contribution provides a comprehensive review of the synthesis routes, modification strategies, and biodegradation behavior of PBS, aiming to position it as a viable and sustainable alternative to traditional plastics.

Summary: This study focused on the development and characterization of biocomposites based on a fully bio-based polyester, PBSA, and wheat bran. The composites maintained similar processability and mechanical properties to virgin PBSA with up to 15 wt.% bran content. The biodegradation tests showed bran's capacity to improve the PBSA biodegradation rate, likely due to the hygroscopic bran swelling and increased polymeric matrix-seawater interfacial area.

Summary: A series of multiblock copolymers with a combination of biomass-originated and biodegradable poly(butylene succinate) (PBS) and poly(2-pyrrolidone) (PA4) units were synthesized with different mean degrees of polymerization (mDP) for each unit. The multiblock structure allows the two components to mix in solution-cast films, despite their inherent immiscibility. The mechanical properties of the films were found to be highly dependent on the mDP of each unit, as demonstrated by tensile tests. The copolymer film with the lowest mDP for each unit (PBS: 17, PA4: 10) was transparent and exhibited high elongation at break (>400%) and high tensile stress (39.5 MPa) with strain hardening. Films with 50% or higher crystallinity were brittle and opaque, while a decrease in crystallinity resulted in higher elongation, as revealed by wide-angle X-ray diffraction measurements.

Summary: This study investigates the preparation of biodegradable polyesters using immobilized lipases on different solid supports. The results demonstrate that the nature of the solid support significantly affects the catalytic activity and effectiveness of the lipases towards polycondensation reactions, resulting in variations in molecular weight and crystallinity of the polyesters.
