AROMATIC OLIGOESTERS Russian patent published in 2009 - IPC C07C43/02 C07C43/267 C07C43/285 C07C43/29 C08G65/40

Abstract RU 2373180 C1

FIELD: chemistry.

SUBSTANCE: invention relates to high-molecular compounds, particularly to aromatic oligoesters, which can be used as oligomers for producing polycondensed polymers. Description is given of aromatic oligoesters of formula: , where n ranges from 1 to 20. Also described is a method of producing said oligomers, involving reacting 3,3-di(4-oxyphenyl)phthalide with 1,1-dichloro-2,2-di(4-chlorophenyl)ethylene in an aprotic dipolar solvent - dimethylsulphoxide at 150°C in an atmosphere of inert gas for 4 hours.

EFFECT: use of proposed oligoesters allows for obtaining a block of copolyesters with high value of intrinsic viscosity and molecular weight, thermal stability and good deformation-strength properties.
