In response to mounting global concerns such as CO emissions, environmental pollution, and the depletion of fossil resources, the field of polymer science is shifting its focus toward sustainability. This research investigates the synthesis of poly(butylene adipate)-co-(dilinoleic adipate) (PBA-DLA) copolymers using two distinct methods: bulk polycondensation and polycondensation in diphenyl ether. The objective is to assess the environmental impact, chemical structure, composition, and key properties of the resulting copolymers, with a particular emphasis on determining the viability of bulk synthesis as a more sustainable approach. Various analytical methods, including nuclear magnetic resonance spectroscopy, Fourier transform infrared spectroscopy, and size exclusion chromatography, were employed to confirm successful copolymerization and highlight differences in molecular weight and microstructure. Additionally, thermal and dynamic mechanical analyses were conducted to thoroughly characterize the copolymers' properties. This research provides significant findings into the sustainable production of PBA-DLA copolymers, offering a more environmentally friendly approach without compromising product quality or performance.
为应对诸如一氧化碳排放、环境污染和化石资源枯竭等日益严重的全球问题，聚合物科学领域正将重点转向可持续发展。本研究采用两种不同方法研究聚（己二酸丁二酯）-共-（二亚油酸己二酸酯）（PBA-DLA）共聚物的合成：本体缩聚和在二苯醚中进行缩聚。目的是评估所得共聚物的环境影响、化学结构、组成和关键性能，特别强调确定本体合成作为一种更可持续方法的可行性。采用了各种分析方法，包括核磁共振光谱、傅里叶变换红外光谱和尺寸排阻色谱，以确认成功共聚并突出分子量和微观结构的差异。此外，还进行了热分析和动态力学分析，以全面表征共聚物的性能。本研究为PBA-DLA共聚物的可持续生产提供了重要发现，提供了一种更环保的方法，同时不影响产品质量或性能。
