METHOD FOR SYNTHESIS OF POLYORGANYLHYDROXYELEMENTOXANES Russian patent published in 1997 - IPC

FIELD: chemistry of polymers. SUBSTANCE: hydrolysis of alkoxide Э(OR)n where Э - chemical element at valency 3-5; R - C1-C6-alkyl is carried out at 120-200 C by addition of water up to mole ratio water : alkoxide = (0.7-1.5): 1 and volatile products were distilled off. Preferably, to take 0.01-5 weight p. p. solvent and/or 0.001-2 weight p. p. additions promoting hydrolysis or modifying polyorganylhydroxyelementoxanes per 1 weight p. alkoxide. EFFECT: increased yield, broadened assortment of products. 2 cl, 1 tbl
