Powdered aromatic polyetheretherketones and copolyetheretherketones

Plasticheskie massy, 2022
The paper presents the results of investigations on fi nding out the possibility of synthesis of powdered aromatic polyetheretherketones and copolyetheretherketones, combining solubility in some organic solvents and crystallinity. It has been shown that, in certain intervals of monomer content, it is possible to obtain copolyetheretherketones that have
