    摘要： The invention disclosed relates to a process for producing azide-substituted aromatic polymers such as polysulfones, and to certain novel azide-substituted polysulfones so produced. The process involves attaching azide groups onto the aromatic rings of the polymers by first activating the attachment site by direct lithiation or bromination, followed by lithiation. The lithiated intermediates are converted substantially qantitatively to azides by reacting with a suitable azide, preferably tosyl azide, under substantially anhydrous conditions. Novel azide-substituted polysulfones containing from one to about three azide groups per repeat polymer unit were obtained, the degree of azide substitution being determined by the degree of lithiation. The azides may also be converted to other functional derivatives such as primary amines and cross-linked membranes.

    摘要： A new series of wholly aromatic poly(arylene ether ether ketone ketone)s containing pendant sulfonic acid groups (SPAEEKK) were conveniently prepared by potassium carbonate mediated nucleophilic polycondensation reactions of inexpensive commercially available monomers: 1,3-bis(4-fluorobenzoyl)benzene (BFBB), sodium 6,7-dihydroxy-2-naphthalenesulfonate (DHNS), and 4,4′-biphenol or hydroquinone in N-methyl-2-pyrrolidone (NMP) at 170° C. FT-IR and NMR were used to characterize the structures and the sulfonate or sulfonic acid contents (SC) of the polymers. Flexible membrane films were obtained by casting N,N-dimethylacetamide (DMAc) solutions of copolymers. Membrane films in acid form were then obtained by treating the sodium form membrane films in 2 N sulfuric acid at room temperature. Glass transition temperatures (Tgs) and decomposition temperatures (Tds) of SPAEEKKs in both sodium and acid forms were determined. Water uptake and swelling ratio values increased with SCs and temperatures. The proton conductivities of acid form membrane films increased with SC value and temperature and reached 5.6×10−2S/cm at 100° C. for SPAEEKK-100.
