Patent ID: 7538080

Claim:
A process for making a compound characterized by consisting of an ethoxylated polyol compound, the polyol compound comprising at least three hydroxy moieties, at least two of the hydroxy moieties consisting of an ethoxy moiety; wherein at least one of the ethoxy moieties comprises an anionic capping unit selected from sulfate, phosphate, or carbonate, or mixtures thereof; wherein the process comprises the steps of (a) ethoxylating a polyol compound comprising at least three hydroxy moieties such that the average degree of ethoxylation of at least two hydroxy moieties is between about 1 and about 100, to form an ethoxylated polyol consisting of at least two ethoxy moieties; (b) reacting at least two of the ethoxy moieties of the ethoxylated polyol with an anionic capping unit to form an anionic ethoxylated polyol; and (c) substituting an anionic capping unit with an amine capping unit to form an aminated anionic ethoxylated polyol.
