| abstract | Use of an ortho ester-based polymer having the general formula wherein R 1 is hydrogen or a hydrocarbon group having 1 to 4 carbon atoms, R 2, R 3 and R 4 are independently a group, the C 3 -C 4 alkyleneoxy groups and / or ethyleneoxy groups in any order, and an end group Y in which it is independent is hydrogen, a hydrocarbyl group having 1 to 30 carbon atoms, a group - (CH 2 ) z NR 5 R 6 or - (CH 2 ) z N + R 5 R 6 R 7, wherein R 5, R 6 and R 7 each independently represents an alkyl group having 1-22 carbon atoms or -CH 2 CH 2 OH and z = 2 or 3, with the proviso that at least one of R 2, R 3 and R 4 comprises at least one block of at least 4 alkyleneoxy on average having 3 and / or 4 carbon atoms, and with the proviso that when Y = hydrogen, at least one ethyleneoxy or alkylenoxy group is linked to Y, or a di- or polycondensate of the polymer via free hydroxy groups in R2, R3 or R4 as water / oil-E demulsifier mulsionen. |
