Biobased Polyester(生物基聚酯)研究综述
Biobased Polyester 生物基聚酯 - This procedure was applied on samples whose ΔHm0 values are already available in the literature, but also on more recent biobased polyesters whose thermal properties are still under investigations. [1] In this study, a 100% biobased polyester has been prepared by a one-pot and solvent-free synthesis, starting from 2,5-furandicarboxylic acid and 1,5-pentanediol. [2] Almost all biobased polyesters are semicrystalline polymers with relatively low glass transition temperature (Tg). [3] A unique strategy for the formation of furan-2,5-dicarboxylic acid (FDCA)-derived esters with methanol and ethylene glycol in concentrated solutions was reported using a six-membered ring acetal of (5-hydroxymethyl)furfural (HMF) with 1,3-propanediol in order to improve the economics for the production of polyethylene 2,5-furandicarboxylate (PEF), a biobased polyester. [4]该程序适用于 ΔHm0 值已在文献中提供的样品，但也适用于热性能仍在研究中的较新的生物基聚酯。 [1] 在这项研究中，从 2,5-呋喃二甲酸和 1,5-戊二醇开始，通过一锅法和无溶剂合成制备了 100% 生物基聚酯。 [2] 几乎所有的生物基聚酯都是玻璃化转变温度 (Tg) 相对较低的半结晶聚合物。 [3] 报道了使用 (5-羟甲基) 糠醛 (HMF) 的六元环缩醛与 1 ,3-丙二醇，以提高生产聚乙烯 2,5-呋喃二甲酸酯 (PEF) 的经济性，这是一种生物基聚酯。 [4]
