A new monomer, (2,5-dimethoxy)phenylhydroquinone (DMPH), was prepared in a two-step synthetic procedure. One aromatic poly(ether ether ketone)s with 2,5-dimethayy phenyl side group (DMP-PEEK) was synthesized via an aromatic nucleophilic substitution reaction with 4,4''''''''-difluorobenzopherone (DFB). Poly(ether ether ketone)s with 2,5-dihydroxy phenyl side group (DHP-PEEK) was obtained via hydrolysis of methoxy group on the DMP-PEEK. Both of the high molecular weight polymers could be obtained despite the steric effect of the bulky pendant groups. The two polymers have good Solubility at room temperature.
