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: 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: By incorporating AD units into PBS chains, the crystallization temperature and crystallinity of PBS can be depressed, while the primary nucleation capability is significantly strengthened without altering crystal modification or crystallization kinetics. The presence of specific interactions among AD units is crucial for the performance of PBSAD, and further investigation may lead to the design of superior PBS copolymers in the future.

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: In this study, flame-retardant poly (butylene succinate) (PBS) composites were developed using a bio-based intumescent flame retardant (IFR) system. Water hyacinth fiber (WHF) was used as a bio-based carbon source, and ammonium polyphosphate (APP) served as an acid source and blowing agent. The results showed that the 15WHF/30APP/PBS composite with a specific WHF to APP ratio and total IFR content exhibited excellent flame retardancy, improved thermal stability, and enhanced mechanical properties.

Summary: This study investigates the effect of mono- and multi-epoxide POSS nanoparticles on the compatibility of PLA/PBS blends from a rheological perspective. The addition of PBS reduces the viscosity and moduli, indicating weak interactions between polymers. However, the presence of MoEpPOSS and MuEpPOSS increases viscosity and moduli by forming complex polymeric structures. MuEpPOSS shows stronger interaction due to its multiple epoxide groups. The introduction of POSS improves dispersion, phase homogeneity, and compatibility, as observed in the Cole-Cole plots, and enhances interfacial adhesion.

Summary: The degradation behavior of PBAT films by different concentrations of Fusarium solani cutinase (FsC) was investigated. It was found that FsC could degrade both the amorphous region and the crystalline region of PBAT films, and its degradation activity was concentration-dependent. High concentration of FsC resulted in significant degradation of PBAT films, while low concentration had less apparent effect. FsC concentration and degradation time did not significantly affect the molecular weight of degraded PBAT.

Summary: Bio-based poly(butylene succinate-co-dodecylene succinate) (PBDSs) were successfully synthesized by adjusting the 1,12-dodecanediol (DD) content using melt polycondensation method. The synthesized copolyesters exhibited good thermal stability and mechanical properties. The relationship between melting temperatures and composition showed a V-shaped distribution, indicating isodimorphism behavior. These polymers are semi-crystalline and may be suitable for making films when the amount of dodecylene succinate unit is 80%.

Summary: Commercially available partially bio-based PBS and PBSA exhibit branching behavior during thermal processing, with PBS showing a higher tendency than PBSA. The presence of fumaric acid moieties contributes to this branching, which can be suppressed by the addition of stabilizers such as phenolic antioxidants.

Summary: Investigating the direct solid state polymerization of PA 612 salt, it was found that reactor design plays a critical role in bypassing the solid melt transition phenomena and maintaining solid state during the reaction. Fossil-based PA 612 products showed better end-group imbalance compared to bio-based ones, which is crucial for achieving high molecular weight in the polymerization process.

Summary: A novel method for determining lipid oxidation using Raman microscopy was developed using a home-made surface-enhanced Raman spectroscopy (SERS) substrate with silver nanoparticles on a glass Petri dish. The degradation of ground pork stored at 5 degrees C was monitored for 16 days, comparing an active packaging with antioxidant properties to a conventional low-density polyethylene (LDPE) film. The SERS method showed significant signal enhancement and better discrimination among samples compared to conventional Raman and the thiobarbituric acid reactive substances (TBARS) method.

Summary: Plastic pollution is a significant environmental challenge and traditional waste management strategies are inadequate for addressing this problem. Enzymatic degradation, particularly using LCCICCG, has shown promise in breaking down PET, the most commonly produced and discarded polyester. However, more efficient PET-hydrolases are needed for larger scale biorefineries.

Summary: Fresh fish is easily perishable and can develop an undesirable odor due to chemical and microbiological degradation. Packaging systems for non-processed fish are being increasingly used to extend its shelf-life and modify the atmosphere surrounding it. Monitoring volatile organic compounds can provide early-stage markers of fish deterioration and various analytical techniques are available for this purpose. This review focuses on the gaseous composition of the atmosphere surrounding packaged fish, degradation pathways of fish constituents, and the factors affecting volatile organic compound composition.

Summary: Accelerated weathering and thermal aging tests were conducted on two low-density polyethylene types to study the effectiveness of different formulations in reducing UV/heat degradation. The study found that neat polyethylene samples showed significant degradation, while stabilized samples showed little to no degradation. LDPE-T exhibited higher photo-oxidation rates due to its comb-like branched structure and higher possibility of intermolecular reactions.
