METHOD OF ORGANOSILICON RESIN PRODUCING Russian patent published in 1997 - IPC

FIELD: chemical technology. SUBSTANCE: resins were synthesized by esterification reaction of organochlorosilane of the general formula: RnSiCl_4-n where: n = 1, 2, 3; R - -CH₃, -C₆H₅, CH₂=CH,-, or their mixture in the presence of tetraethoxysilane. After esterification acidolysis is carried out with acetic acid followed by heating of the prepared reaction mass to the boiling point and exposition at boiling for 1-6 h up to the ready product formation. The latter is washed out in nonpolar organic solvent and solvent is distilled off in the presence of hexamethyldisilazane. Synthesized resin is used as modifying agent of organosilicon and organic rubber, liquid and as binding agent component. EFFECT: improved method of synthesis. 2 cl, 1 dwg, 1 tbl
