  • ALKYLPHENOL-FREE REACTIVE NONIONIC SURFACTANT, PROCESS TO OBTAIN THE ALKYLPHENOL-FREE REACTIVE NONIONIC SURFACTANT, LATEXES OBTAINED BY EMULSION POLYMERIZATION, WATER-BASED COATING COMPOSITION WITH HIGH WATER RESISTANCE, AND USE OF WATER-BASED COATING COMPOSITION
    Publication number: 20230235231
    Abstract: This invention deals with a new alkylphenol ethoxylated free (APE-free) reactive nonionic surfactant with terminal unsaturation in the hydrophobic part comprising at least one of monoesters and diesters and a process to obtain the APE-free reactive nonionic surfactant comprising the alkoxylation step of fatty acid with terminal unsaturation or direct esterification of fatty acid with terminal unsaturation and glycol derivative. Furthermore, emulsion polymerized latexes are disclosed, which are polymerized with an anionic surfactant and a reactive nonionic surfactant of this invention. Latexes prepared according to this invention generated water-based coating compositions with high water resistance.
