Halogen-Containing Copolyarylene Ether Ketones

Copolyarylene ether ketones based on a mixture of bisphenols 1,1-dichloro-2,2-di(4-oxyphenyl)ethylene and 1,1-dichloro-2,2-di(3,5-dibromo-4-hydroxyphenyl)ethylene with 4,4'-dichlorodiphenylketone have been obtained by high-temperature polycondensation in an aprotic dipolar solvent of N,N-dimethylacetamide. The structure and structure of the synthesized copolymers have been studied using the methods of X-ray diffraction analysis, IR spectroscopy, and turbidimetric titration. Basic physical and mechanical properties have been studied, which confirmed that these copolyarylene ether ketones can be used as highly heat-resistant structural polymer materials.
