Preparation of aromatic heterocyclic polymers
摘要:
Heterocyclic aromatic polymers are rapidly formed by contacting one or more appropriate multifunctional aromatic monomers, such as a diaminobenzenediol, a terephthaloyl halide and/or an aminohydroxybenzoic acid, with a sulfonic acid, as the solvent, and a dehydrating agent.
