DICARBOXY GROUP-CONTAINING ORGANOSILICON COMPOUNDS AND THEIR USE Russian patent published in 2007 - IPC C08G77/38 C10M155/02 

FIELD: organosilicon compounds.

SUBSTANCE: invention relates to dicarboxy group-containing polyorganosiloxanes, which can used as anticorrosion additives in treatment of metallic surfaces, and provides polyorganosiloxanes depicted by general formula X(R⁴R⁵SiO)_p(R⁶ASiO)_qY (I), where X represents terminal triorganosilyl group SiR³R²R¹ or OH; Y terminal triorganosilyl group SiR³R²R¹ or H; R¹-R⁶ alkyl or phenyl; A is radical with two carboxyl group of formula -(CH₂)3-CH(COOH)-CH₂COOH (1') or one of the salts thereof; p ranges from more than 0 to 1000; q ranges from 1 to 100; ratio of the number of terminal OH and H groups to number of terminal X and Y groups ranges between 0/100 to 75/100. Invention also discloses method of preparing above-defined compounds, anticorrosive treatment method, and aqueous lubricating solution.

EFFECT: expanded synthetic possibilities and increased assortment of organosilicon special-destination materials.
