AROMATIC OLIGOESTERS AND SYNTHESIS METHOD THEREOF Russian patent published in 2012 - IPC C07C317/22 C07C41/30 C08G75/23 

FIELD: chemistry.

SUBSTANCE: invention relates to high-molecular weight compounds, particularly aromatic oligoesters of general formula , where n=1-20. The invention also relates to a method of producing said oligoesters, which involves reaction at the first step of 1,1-dichloro-2,2-di(n-oxyphenyl)ethylene with 4,4'-dichlorodiphenyl ketone in an aprotic dipolar solvent (dimethylsulphoxide) at 140°C in an atmosphere of an inert gas for 1 hour, and then at the second step, 4,4'-dichlorodiphenyl sulphone is added to the formed dimer and the reaction takes place at temperature 160°C for 3 hours.

EFFECT: disclosed oligoesters can be used as oligomers for producing polycondensation polymers.
