HALOGEN-CONTAINING OLIGOETHERKETONES Russian patent published in 2008 - IPC C07C43/02 C07C43/29 C07C43/275 C07C43/285 C08G65/40

Abstract RU 2318794 C1

FIELD: polymers.

SUBSTANCE: invention relates to high molecular compounds in particular aromatic oligoetherketones of formula , wherein n = 1-20, useful in production of polycondensation polymers. Target compounds are obtained by interaction of 4,4'-dichlorodiphenylketone with 1,1,-dichloro-2,2-di(n-oxyphenyl)ethylene in aprotic dipolar solvent (dimethylsulfoxide) at 140°C in inert gas atmosphere.

EFFECT: copolyetherketones with high viscosity and molecular mass, increased thermal and heat resistance, and fire-retarding.
