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 (T g s) and decomposition temperatures (T d s) 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 −2 S/cm at 100° C. for SPAEEKK-100.

It was surprisingly found that PEKK polymers formed using a specifically adapted nucleophilic synthesis route, in which different monomers are added in to the polymerization reaction at different points during the synthesis, had lower glass transition temperatures (“Tgâ€?) and increased crystallinities, relative to PEKK polymers formed using traditional nucleophilic synthesis routes (“traditional PEKK polymersâ€?). Furthermore, compared with PEKK polymers synthesized using an electrophilic synthesis routes, the PEKK polymers described herein and significantly lower halogen content. The synthesis routes includes a first heating of a first monomer blend in a reaction mixture, a subsequent first addition of a second monomer blend to the reaction mixture, and a second heating of the reaction mixture subsequent to the first addition.

It was surprisingly found that PEKK polymers formed using a specifically adapted nucleophilic synthesis route, in which different monomers are added to the polymerization reaction at different points during the synthesis, had lower glass transition temperatures ('Tg') and increased crystallinities, relative to PEKK polymers formed using traditional nucleophilic synthesis routes ('traditional PEKK polymers'). Furthermore, compared with PEKK polymers synthesized using an electrophilic synthesis routes, the PEKK polymers described herein and significantly lower halogen content. The synthesis routes includes a first heating of a first monomer blend in a reaction mixture, a subsequent first addition of a second monomer blend to the reaction mixture, and a second heating of the reaction mixture subsequent to the first addition.

It was surprisingly discovered that by selectively controlling the relative amounts of reactants during the synthesis, PEKK polymers having unexpectedly lower melt viscosities can be obtained. More particularly, by selectively controlling the relative amounts of monomers used to form recurring units of the PEKK polymer, in conjunction with selective control of other reaction components, the resulting PEKK polymers had reduced viscosities, relative to PEKK polymers synthesized by using tradition reaction schemes (“traditional PEKK polymersâ€?). By providing PEKK polymers with lower melt viscosities, the PEKK polymers described herein have improved processability.
