Compounds based on polyether-modified polybutadiene, wherein the polyether-modified polybutadiene comprises repeat units selected from the group consisting of the divalent radicals where A is in each case independently a monovalent organic radical or a hydrogen radical, preferably in each case independently selected from the group consisting of monovalent hydrocarbon radicals having 1 to 6 carbon atoms, more preferably in each case independently selected from the group consisting of alkyl radicals having 1 to 4 carbon atoms; B is in each case independently selected from the group consisting of radicals of the formula preferably in each case independently selected from the group consisting of radicals of the formula R 1 is in each case independently selected from the group consisting of monovalent hydrocarbon radicals having 1 to 16 carbon atoms, preferably in each case independently an alkyl radical having 1 to 16 carbon atoms or a phenyl radical, more preferably in each case independently a methyl radical, an ethyl radical or a phenyl radical; R 2 is a radical of the formula -CH 2 -O-R 3; R 3 is in each case independently selected from the group consisting of monovalent hydrocarbon radicals having 3 to 18 carbon atoms; preferably in each case independently an allyl radical, a butyl radical, an alkyl radical having 8 to 15 carbon atoms or a phenyl radical that may be substituted by monovalent radicals selected from hydrocarbon radicals having 1 to 4 carbon atoms; more preferably a tert-butylphenyl radical or an o-cresyl radical; R 4 is hydrogen; and m, n, o, p and q are each independently 0 to 300, preferably 0 to 200, more preferably 0 to 100, with the proviso that the sum total of m, n, o, p and q is greater than 1, preferably greater than 5, more preferably greater than 10; including every permutation of the repeat units,,,, and and of the repeat units in the B radical, with the proviso that the sum total of all repeat units, and divided by the sum total of all repeat units,,,, and is >0%, characterized in that the radical B has at least one ester group.
