Influence of Copolycondensation Conditions on the Synthesis and Properties of Aromatic Copolyesulphonketones

Abstract:

The paper investigates the dependence of the reduced viscosity and some properties of aromatic copolyethersulfone ketones on the chemical structure of diphenols and activated dihaloid compounds on the conditions of copolycondensation processes. It is shown that the course of copolycondensation processes and important performance characteristics of products are significantly influenced by the chemical structures of the starting monomers and the order of their introduction into the reaction.
