“…To evaluate the biodegradability of the copolyesters in a short time scale, enzymatic degradation was performed. It is well known that the degradation behavior is significantly affected by the polymer micro‐ and condensed structures such as stereochemistry, hydrophilicity/hydrophobility balance, flexibility of chains, and the morphology such as crystallinity, size and the number of crystallites and usually initiated from amorphous domains 43. In this study, enzymatic degradation is expressed as the percentage of weight loss, and the lipase of P. cepacia was utilized for analyzing the enzymatic degradation of copolyesters at constant temperature of 37°C.…”

The weight loss of the PBSGLA copolyesters during enzymatic degradation process is presented in Figure 7. It is clear that the PBSGLA copolyesters show significant weight loss due to the more content of LA units and lower degree of crystallinity.…”

A series of aliphatic biodegradable poly (butylene succinate-co-ethyleneoxide-co-DL-lactide) copolyesters were synthesized by the polycondensation in the presence of dimethyl succinate, 1,4-butanediol, poly(ethylene glycol), and DL-oligo(lactic acid) (OLA). The composition, as well as the sequential structure of the copolyesters, was carefully investigated by 1 H-NMR. The crystallization behaviors, crystal structure, and spherulite morphology of the copolyesters were analyzed by differential scanning calorimetry, wide angle X-ray diffraction, and polarizing optical microscopy, respectively. The results indicate that the sequence length of butylene succinate (BS) decreased as the OLA feed molar ratio increasing. The crystallization behavior of the copolyesters was influenced by the composition and sequence length of BS, which further tuned the mechanical properties of the copolyesters. The copolyesters formed the crystal structures and spherulites similar to those of PBS. The incorporation of more content of ethylene oxide (EO) units into the copolyesters led to the enhanced hydrophilicity. The more content of lactide units in the copolyesters facilitated the degradation in the presence of enzymes. The morphology of the copolyester films after degradation was also studied by the scanning electron microscopy.

Biodegradable poly(butylene succinate) (PBS) was blended with cellulose microcrystalline (CMC), cellulose acetate (CA), and cellulose triacetate (CTA), respectively, to improve its properties and reduce its cost. The differences in solid-state properties and enzymatic degradation were investigated using FTIR, DSC, XRD, and SEM analysis. SEM images show that the fillers stick up above the matrix and form some pores in both PBS/CMC and PBS/CA blends because of their poor compatibility. Whereas fine particles of PBS and CTA are uniformly mixed and tightly packed together. The degree of crystallinity decreases for PBS/ CTA blends, thereby showing that CTA molecules destroy the crystal uniformity. Young's modulus is increased at average values of 43% after blending. The weight loss ratios of PBS/CMC and PBS/CA blends both reach approximately 85% after 4 h. SEM images show that the spherulitic texture in the surface easily formed cracks and holes and contributed to enzymolysis. In PBS/CTA samples, the weight loss ratio declined to 16% after 4 h. The surfaces are smooth and the enzymolysis occurs only on the surface.

“…Crystallization kinetics plays an important role in these properties of semicrystalline polymers. For example, it has been found that the melt‐quenched PBS showed slower hydrolytic degradation rate than the isothermally crystallized PBS although they had similar degree of crystallinity . The difference of biodegradation rate in the two samples was attributed to the different crystallization kinetics.…”

Nonisothermal crystallization behaviors of both poly(butylene succinate) (PBS) and poly(ethylene glycol) (PEG) segments within PBS‐PEG (PBSEG) multiblock copolymers were investigated by differential scanning calorimetry (DSC). The nonisothermal crystallization kinetics of both PBS and PEG segments were analyzed by Avrami, Ozawa, and Mo methods. The results showed that both of Avrami and Mo methods were successful to describe the nonisothermal crystallization kinetics of PBS and PEG segments. The results of crystallization kinetics indicated that the crystallization rate of PBS segment decreased with PBS segment content and/or LPBS, while that of PEG segment decreased with Mn,PEG or FPEG. © 2014 Wiley Periodicals, Inc.
