“…Several examples can be cited, such as chitin, poly(lactic acid), cellulose acetate, starch, and more incipiently poly(butylene succinate) (PBS) . This polymer is obtained by the polycondensation of 1,4‐butanediol and succinic acid . PBS is an aliphatic, thermoplastic, and crystalline polyester with excellent thermal and mechanical properties .…”

Controlled‐release fertilizer is one of the most critical tools in agribusiness for decreasing environmental impacts. Thus, the development of bio‐based systems able to induce the slow release of fertilizers has become the focus of numerous researchers. In this sense, this work presents a slow‐release fertilizer prepared by melt mixing of poly(butylene succinate) filled with 30 wt % urea and 5 wt % montmorillonite clay. The obtained materials were characterized using FTIR, XRD, and SAXS. Also, the release of urea was investigated using gravimetric and spectrophotometric tests. Finally, a vegetable growth analysis was performed to evaluate the development of lettuce (Lactuca sativa L.). The best composite material can increase the diameter of the lettuce by 67%, whereas the conventional use of urea increased this diameter by 48%. Therefore, the presented materials are useful as fertilizer systems.

“…PCL was blended with various other biodegradable polymers in a number of studies [12][13][14][15][16][17][18][19][20][21][22]. Amongst various biodegradable polymers, PBS was the most interesting aliphatic polyester due to its relatively good melt processability, thermal and chemical resistance, biodegradability, and excellent mechanical properties, closely comparable to those of the widely-used polyethylene (PE) and polypropylene (PP) [4,5,[15][16][17][18][19][20][21][23][24][25][26][27][28][29][30][31][32][33][34][35][36]. Double crystalline PCL/PBS blends are particularly interesting because each component has an influence on the crystallization behaviour of the other component.…”

Abstract. Biodegradable polymers received considerable attention due to their contribution in the reduction of environmental concerns and the realization that global petroleum resources are finite. The development of double crystalline biobased blends such as poly(ε-caprolactone) (PCL) and poly(butylene succinate) (PBS) are particularly interesting because each component has an influence on the crystallization behaviour of the other component, and thus influences the strength and mechanical properties of a polymer blend. The lack of miscibility between PCL and PBS constitutes a bottleneck, and efforts have been made to improve the miscibility through the inclusion of copolymers. Having realized that incorporating conductive nanofillers such as carbon nanotubes (CNTs), (especially when the CNTs are functionalized or used as a masterbatch i.e., polycarbonate/MWCNTs masterbatch), into biopolymer matrices, can enhance the thermal and mechanical properties, as well as electrical and thermal conductivity, a lot of research was aimed at the production of bionanocomposites. This review paper discusses the properties of PCL, PBS, their blends, and their CNTs containing nanocomposites.

“…M n determined by P‐NMR varied between 8500 and 15,000 g mol −1 and this technique gave a more accurate estimation of the aliphatic copolyesters molar mass. However, this method based on the quantification of end‐groups did not take into account the possible macrocycles that could have been produced during the polyester synthesis and were present on the polymer matrix but undetectable by P‐NMR analysis …”

Fully biobased aliphatic random poly(1,3-propylene succinate-ran-1,3-propylene adipate) (PPSA) copolyesters with high molar mass were synthesized with different macromolecular architectures based on various succinic acid/adipic acid (SA/AA) molar ratio, by transesterification in melt. Titanium (IV) isopropoxide was used as an effective catalyst. All synthesized copolyesters were fully characterized by different chemical and physicochemical techniques including NMR, size exclusion chromatography, FTIR, wide angle X-ray scattering, differential scanning calorimetry, and thermogravimetric analysis. The final copolyesters molar compositions were identical to the feed ones. The different sequences based on succinate and adipate segments were randomly distributed along the chains. All the corresponding copolyesters showed an excellent thermal stability with a degradation onset temperature higher than 290 8C, which increased with the adipate content.According to their compositions and architectures, PPSA copolyesters can exhibit or not a crystalline phase, at room temperature. T g of copolyesters decreased with the adipate content due to the decrease in the chains mobility, following the Gordon-Taylor relation. PPSA showed a pseudo eutectic melting behavior characteristic of an isodimorphic character. Finally, PPSA copolyesters were not able to crystallize during the cooling or the second heating run, due to the 1,3-propanediol chemical structure, which led to amorphous materials with the exception of the polyester based solely on AA.
