## Abstract A series of wellβdefined poly(ether ketone ketone) (PEKK)/sodium sulfonated poly(aryl ether ketone) (SβPAEK) block copolymers of high molecular weights was prepared by direct nucleophilic polymerization of hydroquinone with sodium 5,5β²βcarbonylbis(2βfluorobenzene sulfonate) (**1**) and
Copolymerizations of p-dichlorobenzene (DCB)/4-bromophenyl ether (BPE), DCB/4,4Π-dibromobiphenyl (DBB), and DBB/BPE pairs with sodium sulfide under high temperature (270 -290Β°C) utilizing N-methyl-2-pyrrolidinone (NMP) as solvent were carried out to give C(DCB/BPE), C(DCB/DBB), and C(DBB/BPE) copoly
