The invention relates to the use of compounds of the general formula (VII), wherein R 1 , R 2 , R 3 , R 4 , R 5 are identical or different radicals selected from linear or branched, saturated, mono- or polyunsaturated alkyl, aryl, alkylaryl or arylalkyl radicals having 1 to 20, in particular 1 to 10 C atoms, haloalkyl groups having 1 to 20 C atoms, siloxy groups and triorganosiloxy groups; R 6 is at least one radical selected from the group CH 2 -CH 2 - (CH 2 ) a -A or CH = CH- (CH 2 ) a -A wherein a is an integer between 0 and 10; and A represents a radical which is selected from polyoxyalkylene radicals or linear, branched or cyclic, saturated, mono- or polyunsaturated alkyl, aryl, alkylaryl or arylalkyl radicals having 1 to 100, in particular 1 to 50, C atoms which are optionally heteroatoms contain; Z represents a triorganosilyl radical; m is an integer between 5 and 300; n is an integer between 5 and 300; o is an integer between 2 and 300; wherein the sum (n + o) ≦ 400; p is an integer between 2 and 50, as stabilizers in the production of polyurethane foams. |
