METHOD OF PRODUCTION OF THE STATISTICAL INTERPOLYMERS OF THE POLYPHENYLENESULFIDESULFONS Russian patent published in 2007 - IPC C08G75/20 C08G75/14 

FIELD: chemical industry; electronic industry; space-and-aircraft industry; electrical industry; other industries; methods of production of the interpolymers of polyphenylenesulfidesulfons.

SUBSTANCE: the present invention is pertaining to the method of production of the interpolymers of polyphenylenesulfidesulfons by the reaction of the dihaloiddiphenylsulfon with the bisphenol used for manufacture of the constructional products intended for usage in electronics engineering, the electrical engineering, aerospace engineering, etc. The method of production of the indicated interpolymers is exercised in one stage and allows to realize the synthesis of the interpolymers with the preset ratio of the sulfidic and sulfonic fragments with the increased flowability of the melt and the stability of the properties consists in interaction of the mixture of bisphenol, the alkaline metal sulfide and the alkaline metal carbonate at the molar ratio of the bisphenol and the sulfide from 0.95:0.05 up to 0.01:0.99 and the ratio of the alkaline metal carbonate from 0.05 up to 1.3 mole per one mole of dihaloidarylsulfon at the temperature of boiling of the organic solvent.

EFFECT: the invention allows to realize the synthesis of the interpolymers with the preset ratio of the sulfidic and sulfonic fragments with the increased flowability of the melt and the stability of the properties.
