CHLORINE CONTAINING AROMATIC OLIGOESTERS Russian patent published in 2010 - IPC C07C43/29 C07C43/275 C07C43/285 C07C43/295 C08G65/40 C08G65/42

Abstract RU 2382756 C2

FIELD: chemistry.

SUBSTANCE: invention relates to high-molecular compounds, particularly to aromatic oligoesters of general formula , where n=2-20. The compound is obtained by reacting 1,1-dichloro-2,2-di(4-oxyphenyl)ethylene with 1,1-dichloro-2,2-di(4-chlorophenyl)ethylene in an aprotic dipolar dimethylsulfoxide solvent in an inert gas atmosphere.

EFFECT: when proposed oligomers are used in practice, block-copolyesters are obtained, having good molecular mass values, high fire- and heat-resistance, retain good dielectric properties in a wide temperature and frequency range, set during thermal treatment with improvement of many operational characteristics.
