Kind Code:
A1
Abstract:
A class of multi-mixed composite salt monomers having anti-oxidation stability and polybenzodiazole liquid crystal polymers, and preparations and applications thereof. The structure of the multi-mixed composite salt monomer is represented by formula (I), (II) or (III). Further disclosed are a preparation method for a multi-mixed composite salt monomer, an application of the multi-mixed composite salt monomer in a self-condensation polymerization preparation of a polybenzodiazole liquid crystal polymer and fiber thereof, and a resulting polybenzodiazole liquid crystal polymer and a fiber thereof. The structure of the polybenzodiazole liquid crystal polymer is represented by formula (V), (VI) or (VII). The multi-mixed composite salt monomer integrates the structure and potential performance of a material into one, and has excellent anti-oxidation stability; the monomer is applied in the self-condensation polymerization preparation of a modified PBO composite fiber, and can effectively solve the comprehensive performance of a material, and has the advantages of having a fast polymerization speed, unique fiber coagulation device and process, high productivity, convenient operation, low costs and so on.
