Enzymatic polymerization provides an excellent opportunity for the conversion of renewable resources into polymeric materials in an effective and sustainable manner. A series of furan-based copolyesters was synthesized with up to 35 kg mol , by using Novozyme 435 as a biocatalyst and dimethyl 2,5-furandicarboxylate (DMFDCA), 2,5-bis(hydroxymethyl)furan (BHMF), aliphatic linear diols, and diacid ethyl esters as monomers. The synthetic mechanism was evaluated by the variation of aliphatic linear monomers and their feed compositions. Interestingly, there was a significant decrease in the molecular weight if the aliphatic monomers were changed from diols to diacid ethyl esters. The obtained copolyesters were thoroughly characterized and compared with their polyester analogs. These findings provide a closer insight into the application of enzymatic polymerization techniques in designing sustainable high-performance polymers.
酶聚合为有效且可持续地将可再生资源转化为聚合材料提供了极好的机会。使用诺维信 435 作为生物催化剂，通过二甲酯 2,5-呋喃二甲酸酯（DMFDCA）、2,5-双（羟甲基）呋喃（BHMF）、脂肪族线性二醇和二酸乙酯作为单体，合成了一系列高达 35kg·mol 的呋喃基共聚酯。通过改变脂肪族线性单体及其进料组成来评估合成机理。有趣的是，如果将脂肪族单体从二醇变为二酸乙酯，分子量会显著降低。对得到的共聚酯进行了彻底的表征，并与它们的聚酯类似物进行了比较。这些发现为酶聚合技术在设计可持续高性能聚合物中的应用提供了更深入的了解。
