SYNTHESIS OF AROMATIC POLY(ETHER KETONE)S WITH FERROCENE UNITS IN THEMAIN-CHAIN

Aromatic poly(ether ketone)s with ferrocene units in the main chain we re prepared by direct polycondensation of 1,1'-ferrocenedicarboxylic a cid with diphenyl ether or 1,4-diphenoxybenzene using various catalyst s such as trifluoromethanesulfonic acid (triflic acid), a combination of methanesulfonic acid/P2O5 (Eaten's reagent) or a combination of tri flic acid/P2O5. Polycondensations at room temperature for 24 h gave po ly(arylene ether ketone)s with inherent viscosities up to 40 mL g(-1). Monoacylation of diphenyl ether with ferrocenecarboxylic acid was stu died in detail in order to show the efficiency of polymer formation em ploying Eaten's reagent as catalyst and solvent.
