POLYCONDENSATION MONOMER Russian patent published in 2010 - IPC C07C39/19 C07C43/29 C07C43/275 C07C43/285 C08G65/42 

FIELD: chemistry.

SUBSTANCE: invention relates to a novel chemical composition, specifically to 1,1-dichloro-2,2-di-4[4'{1'1'-dichloro-2'-(4"-oxyphenyl)ethylenyl}phenoxyphenyl]ethylene of formula as a polycondensation monomer. The problem is solved through synthesis of a compound by reacting 1,1-dichloro-2,2-di(4-oxyphenyl)ethylene with 1,1 -dichloro-2,2-di (4-chlorophenyl)ethylene in dimethylsulphoxide in an inert atmosphere. Use of the proposed monomer enables to obtain polyesters with good molecular weight values, high fire- and thermal stability, retain good dielectric properties in a wide temperature and frequency range, easily dissolve in common organic solvents and can be processed into articles using conventional processing methods.

EFFECT: obtaining a novel chemical compound.
