New halogen-containing oligoesterketones have been synthesized by high-temperature polycondensation in an aprotic dipolar solvent in an inert gas atmosphere, and methods have been developed for producing new monomers and oligomers suitable for the production of aromatic polyesters based on halogen-containing monomers with the replacement of the traditional 4,4-difluorobenzophenone with a chlorine-containing monomer. The substantiation of the choice of the research task, the technical and economic aspects of the problem and the ways of its solution are presented. The task of synthesizing monomers and oligomers for the subsequent polymerization of aromatic polyesters is due to the importance of ensuring the relationship of the properties of the synthesized polymer from the list and characteristics of the base materials used. Thus, methods for obtaining monomers and oligomers based on them have been developed, correlation dependences of the properties of the obtained materials on the composition and quantity of fillers used have been investigated. Nucleophilic substitution reactions for the production of oligomers are described. The structures of the obtained monomers and oligomers are determined and possible areas of their application are established, data on the study of the properties of the obtained materials by IR spectroscopy, elemental and X-ray diffraction analysis, TGA, DSC, etc. are presented. The practical significance and applicability of the obtained materials and products for various purposes is proposed, taking into account the requirements for materials with high heat resistance, physico-mechanical, operational characteristics.

As part of solving the problem of creating recipes for the synthesis of domestic superconstruction polymers, work was carried out on the synthesis of aromatic polyester materials with a complex of valuable performance characteristics. It has been established that it is possible to improve the economic performance of the PCM synthesis process based on aromatic polyesters by replacing the traditional 4,4'-difluorobenzophenone monomer with a chlorine-containing functional analog, which makes it possible to synthesize new materials with a cost up to 6 times lower than known competitors. The paper studies the features and determines the optimal conditions for the synthesis of new aromatic polyester materials: oligoetherketones and polyetherketones, polyimides and polyeth-erimides, to create binders for the impregnation of glass and carbon reinforcing fillers. It is described that the syn-thesis of polyimides (PI) was carried out by a two-stage method: obtaining a polyamic acid (PAA) and obtaining an insoluble diversified polymer. It has been established that by replacing the expensive dihalide, it is possible to a large extent to reduce the cost of synthesized polymers, increase their yield and manufacturability. A complex of physicochemical studies by various methods has been carried out, the structure of the synthesized polymers has been established, it has been determined that new polyester materials based on poly(aryleneetherketones) and pol-yetherimides are superior in their basic physicochemical and operational properties to industrial analogous poly-ester superstructural materials.
