Zusammenfassung:	FIELD: chemistry; high molecular compounds. ^ SUBSTANCE: aromatic ether-ketone oligomers are used as oligomers for obtaining polycondensing polymers and mean of production of them. where n=1-20 oligomers are obtained from the reaction 4,4'-dichlorodiphenylketone with 1,1-dichloro-2,2-di(3,5-dibromo-n-oxyphenyl)ethylene in an aromatic dipolar solvent (dimethylsulfoxide) at 140°C in an atmosphere of an inert gas. ^ EFFECT: obtaining of copolyester-ketones with high values of reduced viscosity and molecular mass, higher thermal stability, and refractoriness. ^ 1 cl, 4 ex
