A synthetic biopolymer derived from furandicarboxylic acid monomer and hydroxyethyl-terminated poly(ether sulfone) is presented. The synthesis involves 4,4'-dichlorodiphenyl sulfone and 4,4-dihydroxydiphenyl sulfone, resulting in poly(butylene furandicarboxylate)-poly(ether sulfone) copolyesters (PBFES) through melt polycondensation with titanium-catalyzed polymerization. This facile method yields segmented polyesters incorporating polysulfone, creating a versatile group of high-temperature thermoplastics with adjustable thermomechanical properties. The PBFES copolyesters demonstrate an impressive tensile modulus of 2830 MPa and a tensile strength of 84 MPa for PBFES55. Additionally, the poly(ether sulfone) unit imparts a relatively high glass transition temperature (), ranging from 36.6 °C for poly(butylene 2,5-furandicarboxylate) to 112.3 °C for PBFES62. Moreover, the complete amorphous film of PBFES exhibits excellent transparency and solvent resistance, making it suitable for applications, such as food packaging materials.
本文提出了一种由呋喃二甲酸单体和羟乙基封端的聚醚砜合成的生物合成聚合物。该合成方法涉及 4,4'-二氯二苯砜和 4,4-二羟基二苯砜，通过钛催化聚合的熔融缩聚反应生成聚（丁烯呋喃二甲酸酯）-聚（醚砜）共聚酯（PBFES）。这种简单的方法可以得到包含聚砜的嵌段聚酯，形成一组具有可调热机械性能的多功能高温热塑性塑料。PBFES 共聚酯的拉伸模量高达 2830 MPa，拉伸强度为 84 MPa（PBFES55）。此外，聚醚砜单元赋予相对较高的玻璃化转变温度（Tg），范围从聚（丁烯 2,5-呋喃二甲酸酯）的 36.6°C 到 PBFES62 的 112.3°C。此外，PBFES 的完全非晶态薄膜具有优异的透明度和耐溶剂性，使其适用于食品包装材料等应用。
