Abstract
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 some crystallinity and remain soluble in some organic solvents. A simplifi ed method for obtaining aromatic polyetherketones and copolyaryleneetherketones has been developed. The high values of thermal and mechanical characteristics enable to recommend the obtained polyetheretherketones and copolyetheretherketones for forming special-purpose products using 3D-technologies.
