<p>Compounds useful in the dual function as surfactants as well as defoaming agents and wetting agents are prepared from the reaction of (I) the reaction product of A) a linking agent of formula 1 R4(Y)3 wherein each Y group is a halogen atom or one Y group is a halogen atom and two Y groups represent an oxygen atom, which is attached to two adjacent carbon atoms in the R4 group to form an epoxy group, and R4 is an alkanetriyl group containing from 3 to 10 carbon atoms; and B) a compound formula (II) R3(EO)n(PO)m(BO)pX wherein R3 is a substituted or unsubstituted, saturated or unsaturated, aliphatic or araliphatic oxy or thio group having from 1 to 36 carbon atoms or a secondary amino group having from 2 to 36 carbon atoms; n is a number of from 0 to 50; m is a number of from 0 to 50; p is a number of from 0 to 50; and X is hydrogen, or a mercapto or amino group in place of a terminal -OH group, provided that when X is mercapto or amino; the sum of n, m, and p must be at least one; the mole ratio of A:B is from about 0:2:1 to about 5:1; and (II) an epoxy compound, isocyanate, phosphate compound, sulfate compound, organic acid, acrylate or methylol urea as a reactant.</p> |
