Abstract

We report here a method for making polyesterether from ethylene glycol. The reaction is catalyzed by a ruthenium complex and liberates H₂ gas and H₂O as byproducts. Mechanistic studies conducted through experiments and DFT computations suggest that the chain growth of the polymerization process involves both dehydrogenation and dehydration pathways stemming from a hemiacetal intermediate, leading to the formation of esters and ethers, respectively. Investigations into the polymerization of other diols have also been conducted, showing that diols with a lower number of carbons between the alcohol groups (propylene glycol, glycerol, and 1,3-propanediol) lead to the formation of polyesterether whereas α,ω-diols containing a higher number of carbons (1,6-hexanediol and 1,10-decanediol) lead to the formation of polyester.

We report here a method for making polyesterethers directly from ethylene glycol, forming water and H₂ gas as the only byproducts.

乙二醇直接合成聚醚的研究

本文报道了一种以乙二醇为原料制备聚醚的方法。该反应由钌络合物催化，并释放H2气体和H2O作为副产物。通过实验和DFT计算进行的机理研究表明，聚合过程的链生长涉及由半缩醛中间体引起的脱氢和脱水途径，分别导致酯和醚的形成。对其他二醇的聚合也进行了研究，表明在醇基（丙二醇、甘油和1,3-丙二醇）之间具有较低碳数的二醇导致聚酯醚的形成，而含有较高碳数的α，ω-二醇（1,6-己二醇和1,10-癸二醇）导致聚酯的形成。本文报道了一种直接从乙二醇制备聚醚的方法，只生成水和氢气作为副产物。
