Summary: | Quaternary ammonium phosphates produced by reacting a dicarboxylic acid with an alkoxylated tertiary amine to prepare an amino-functional polyester, mixing the polyester in the presence of water with a phosphoric acid ester, and reacting the mixture with an alkylene oxide at elevated pressure and temperature. The quaternary ammonium phosphates are useful as anti-static agents for textile fiber materials. |
