<jats:title>Abstract</jats:title> <jats:p>High molecular weight poly(aryl ether)s were successfully prepared by the Pd-catalyzed polycondensation of 2,2-bis(4-hydroxy-3-methylphenyl)propane (I) with 4,4′–dibromobiphenyl (II). The polycondensation proceeded in toluene in the presence of 4 mol% Pd(OAc)2, 6 mol% 2-(di-tert-butylphosphino)biphenyl, and 6 equiv K3PO4 at 90 °C for 24 h, giving the polymer with a number-average molecular weight (Mn) of 18000. The resulting polymers were fully characterized by IR and NMR spectroscopies.</jats:p>
