摘要: 以发烟硫酸和4,4′-二氯二苯砜为原料,通过磺化反应,制得磺化二氯二苯砜,然后利用亲核缩聚反应,调整磺化单体和非磺化单体的比例,与四甲基联苯二酚进行聚合,制取了系列具有不同磺化度的聚醚醚砜,并对聚合物的结构进行了研究.

Abstract: A novel sulfonated poly(ether ether sulfone) derived from 3,3′,5,5′-tetramethylbiphenyl-4,4′-diol was synthesized by direct aromatic nuelecphilic condensation of 3,3′,5,5′-tetramethylbiphenyl-4,4′-diol with various ratios of 3,3′-disulfonate-4,4′-dichlorodiphenylsulfone to 4,4′-dichlorodiphenylsulfone. The polymers have a good thermal stability and solubility in some polar solvents. Most of them can be cast into tough membranes, and the properties of the membranes will be studied in future.

Key words: Sulfonation, Poly(ether ether sulfone)s, Fuel cell, Proton exchange membrane
