METHOD FOR PRODUCTION OF SILOXANE OLIGOMERS Russian patent published in 2006 - IPC C08G77/28 C08G77/26 C08G77/24 C08G77/14 C08G77/06 C08G77/38

Abstract RU 2285017 C2

FIELD: polymers.

SUBSTANCE: described is method for production of siloxane oligomers of general formula I or II , wherein oligomer has at least one functionalized alkyl group in molecule. Claimed method includes oligomerization of haloalkyltrihalosilanes in presence of alcohol and water and optionally cooligomerization with C₁-C₁₈-alkyl-, phenyl, aryl- or alkyltrihalosilanes and/or silicium tetrachloride; and in the further step haloalkyl functionality is optionally modified.

EFFECT: improved method for production of siloxane oligomers.
