Vanillic acid, which is potentially available from lignin, was converted to dibasic acids by etherifying the phenolic hydroxyl group with alkylene dihalides. The dibasic acids were esterified with ethylene glycol and condensed to linear polyesters. The polyesters were converted to fibers by melt spinning. The fibers could be stretched, preferably in a warm water bath, to give fibers with good tenacity
香草酸可能从木质素中获得,通过用亚烷基二卤化物将酚羟基醚化,将其转化为二元酸。二元酸用乙二醇酯化并缩合成线性聚酯。通过熔融纺丝将聚酯转化为纤维。可以拉伸纤维,优选在温水浴中拉伸,以得到具有良好韧度和增加的结晶度的纤维,如双折射测量所示。由乙烯二香草酸获得的聚酯在 210°C 下熔化。但在 80°C 时软化并收缩。
