Use of organosilicon-modified polydienes as de-emulsifiers for crude oil/water emulsions

Use of organosilicon-modified polydienes of the general formula in which Z denotes chain-terminating groups, R in the molecule is identical or different and is hydrogen or a methyl radical, R in the molecule is identical or different and is an optionally fluorinated alkyl or alkylaryl radical having...

Zusammenfassung:	Use of organosilicon-modified polydienes of the general formula in which Z denotes chain-terminating groups, R in the molecule is identical or different and is hydrogen or a methyl radical, R in the molecule is identical or different and is an optionally fluorinated alkyl or alkylaryl radical having 6 to 24 carbon atoms, R in the molecule is identical or different and is the radical (R O-)mY, R comprising alkylene radicals having 2 to 4 carbon atoms with m >/= 2 and Y being an alkyl radical having 1 to 4 carbon atoms, and with, on average w >/= 0, x >/= 0, y >/= 3, a = 0 to 2, b = 0 or 1, 0 < c < 3 and 0 < a + c < 3 as de-emulsifiers for crude oil/water emulsions.I
