Abstract

A new fiber was designed and synthesized by using 2, 5-dihydroxyterephthalic acid instead of terephthalic acid as monomer in the structure of Polyp-phenyl dioxazole (PBO) fiber and introducing homophenic acid as the third monomer. The fiber has a network structure due to the introduction of homophenic acid as the third monomer, and the introduction of two hydroxyl groups on the p-benzene group, which effectively improves the compressive strength of the fiber. This work includes synthesis route, characterization of intermediates by NMR spectroscopy and infrared testing of prepolymers. On the basis of maintaining the excellent properties of PBO fiber, the fiber can effectively increase the compressive properties of PBO fiber and further expand the application prospect of PBO fiber.
