Microplastic has become the focus of environmental pollution recently, especially in seawater. Due to its high crystallinity and hydrophobicity, the degradation rate of poly(butylene succinate) (PBS) is slow. In this paper, a series of poly(butylene succinate‐co‐diethylene glycol succinate) (PBSD) copolymers were synthesized by melt‐polycondensation in order to improve the nonenzymatic hydrolysis of PBS. The contact angle and water uptake content of copolymer were increased obviously when the regular crystalline structure of chain segment was disturbed by diethylene glycol. Rheological tests revealed the microphase separation structure occurred at 130°C. The tensile strength of PBSD40 copolymer was 15 MPa and the elongation at break was more than 700%, and the decomposition temperature was above 370°C. The weight loss of PBSD60 copolymer in acid condition was 98.6% after 49 days at 50°C. However, in neutral condition and simulated seawater, the weight loss was less than 10%. Acid and alkaline catalyzed the hydrolysis of ester bonds. Some holes and cracks appeared at the surface of the samples after degradation from SEM analysis. Thus, PBSD copolymers have the potential to serve as promising water degradable materials.

“…This phenomenon was not significant. 31,32 It is very interesting that the weight loss of copolymer in acid and alkaline solution was completely different. For PBS copolymers, the weight loss in acid after 49 days was 6.4%, but the weight loss of PBSD60 copolymer was 98.6%.…”

The main problem of manufacturing with traditional biodegradable plastics is that it is more expensive than manufacturing with polymers derived from petroleum, and the application scope is currently limited due to poor comprehensive performance. In this study, a novel biodegradable poly(butylene adipic acid/terephthalate-co-glycolic acid) (PBATGA) copolyester with 25–60% glycolic acid units was successfully synthesized by esterification and polycondensation using cheap coal chemical byproduct methyl glycolate instead of expensive glycolic acid. The structure of the copolyester was characterized by ATR-FTIR, 1H NMR, DSC, and XRD; and its barrier property, water contact angle, heat resistance, and mechanical properties were tested. According to the experiment result, the PBATGA copolyesters showed improved oxygen (O2) and water vapor barrier character, and better hydrophilicity when compared with PBAT. The crystallization peaks of PBATGAs were elevated from 64 °C to 77 °C when the content of the GA unit was 25 mol %, meanwhile, the elongation at the break of PBATGA25 was more than 1300%. These results indicate that PBATGA copolyesters have good potentiality in high O2 and water vapor barrier and degradable packaging material.

Designing high‐performance water‐degradable plastics is an important way to address marine microplastic pollution. A series of poly(neopentyl terephthalate‐co‐neopentyl succinate) (PNST) copolymers were synthesized using the one‐step melt‐polycondensation method. The 1H‐NMR results showed that the neopeantyl succinate (NS) and neopeantyl terephthalate (NT) segments were randomly distributed, and the Fox model indicated that they demonstrate good compatibility. The PNST copolymers showed excellent mechanical properties. The tensile strength of poly(neopentyl terephthalate) (PNT) was 50.3 MPa, and the elongation at break was 10.0%. SA segments improved the flexibility of the PNT units, and the elongation at break of PNS was 2200%, which was more than 220 times than that of the PNT copolymer. The PNST copolymer had two decomposition platforms. The fastest decomposition rate of PNS occurred at 450°C, and that of PNT at 500°C. SA units improved the rotation and hydrophilic properties of the chains, which allowed for degradation and reduced the water contact from 102.9° to 68.9°. The weight loss of PNS was more than 20% after degrading in alkaline solution for 49 days, and 1% and 1.9% in neutral and acid solution, respectively. Thus, PNST copolymers are promising water‐degradable materials with good tensile and excellent thermal properties.
