Abstract
Compounds are based on polyether-modified polybutadiene, where the polyether-modified polybutadiene contains repeat units selected from the divalent radicals: The radical B has at least one ester group.
Claims24
A compound that is polyether-modified polybutadiene, wherein the polyether-modified polybutadiene comprises repeat units selected from the group consisting of divalent radicals
- wherein
- A is in each case independently a monovalent organic radical or a hydrogen radical;
- B is in each case independently a radical of the formula (4a)
- R1 is in each case independently a monovalent hydrocarbon radical having 1 to 16 carbon atoms;
- R2 is a radical of the formula —CH2O—R3;
- R3 is in each case independently a monovalent hydrocarbon radical having 3 to 18 carbon atoms;
- R4 is hydrogen or acyl;
- m, n, o, p and q are each independently 0 to 300, with the proviso that a sum total of m, n, o, p and q is greater than 1;
- for every permutation of the repeat units (U), (V), (W), (X), (Y) and (Z) and of repeat units in B, with the proviso that a sum total of all repeat units (U), (V) and (W) divided by a sum total of all repeat units (U), (V), (W), (X), (Y) and (Z) is >0%, and
- wherein B has at least one ester group.
