Abstract

Polymeric compounds useful as low foaming surfactants and defoaming and stabilizing agents for aqueous-and nonaqueous-based compositions, and to 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 R1(X)3 (I) wherein each X group is a halogen atom or one X group is a halogen atom and two X groups represent an epoxy oxygen atom, which is attached to two adjacent carbon atoms in the R1 group to form an epoxy group, and R1 is an alkanetriyl group containing from 3 to 10 carbon atoms; and B) compounds of formula 11 R2(OA)nX (II) wherein R2 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.

and, optionally
C) from about 0.001 to about 50 mole %, based on total moles of A), B), and C), of at least one of the following compounds,
a) a polyol containing at least 3 hydroxyl groups, one or more of which are optionally alkoxylated, and
b) a polyamine containing at least two amino groups, and which can optionally contain alkyleneoxy groups;
wherein the ratio of moles of component A) to the sum of the OH, —SH, and —NHR′ equivalents in components B) plus C) if present is from about 0.6:1 to about 5.0:1;
provided that when component C) is not present, component B) is a mixture of at least two compounds of formula II wherein the R2 group in the first compound (B) a)) is an aliphatic group containing from 1 to 8 carbon atoms, or a phenol or styrenated phenol group, and the R2 group in the second compound B) b)) is an aliphatic group containing from 9 to 36 carbon atoms, and said second compound B) b) is present in from about 0.001 to about 50 mole %, based on the moles of the first compound B)a), and when component C) is present R2 IN formula II contains from 4 to 36 carbon atoms.
