Polymeric compounds useful as low foaming surfactants and defoaming and stabilizing agents for aqueous- and nonaqueous-based compositions, and processes for the preparation of the polymeric compounds, wherein the polymeric compounds are the reaction products of reactants comprising A) at least one linking compound of formula (I): R<1>(X)3, wherein each X group is a halogen atom or one X group is halogen atom and two X groups represent an epoxy oxygen atom, which is attached to two adjacent carbon atoms in the R<1> group to form an epoxy group, and R<1> is an alkanetriyl group containing from 3 to 10 carbon atoms; and B) compounds of formula (II): R<2>(OA)nX, wherein R<2> is an organic group containing from 4 to 36 carbon atoms, n is a number of from 0 to 200, X is -OH, -NHR', or -SH and each OA group is independently an ethyleneoxy, 1,2-propyleneoxy, or 1,2-butyleneoxy group. |
