On the Synthesis of Copolyarylene Ether Ketones by Nucleophilic Substitution Reaction

The dependence of the reduced viscosity of copolyarylene ether ketones on the chemical structure of diols and the conditions for copolycondensation is studied. It was shown that the structure of diols and the order of their introduction into the polycondensation reaction affect the reduced viscosity, impact strength, and temperature characteristics of copolyarylene ether ketones.
