Abstract
Data are given on aromatic copolyether ether ketones obtained from aromatic diols, namely, hydroquinone and diphenylolpropane (Bisphenol A). The copolyethers were synthesized by high–temperature copolycondensation of the corresponding diols with 4,4'–difluorobenzophenol. The dependence of the rheological and thermochemical properties of the polymer samples on the mole ratio of the diphenols was studied for a broad range of monomer concentrations. Enhanced heat resistance along with decreased intrinsic viscosity and glassy point temperature were found for copolyether ether ketones with a greater content of hydroquinone.
