General description
3,3′,4,4′-Biphenyltetracarboxylic dianhydride (s-BPDA) is a rigid symmetric polyamide with a diamine having a long distance between amine groups and reactive endgaps.
Application
s-BPDA can be used in the synthesis of high molecular weight aromatic polyamide fibers. It can also be used in the formation of hybrid nanocomposite films.
