Abstract
This invention provides water-based compositions, particularly coating, ink, fountain solution and agricultural compositions, manifesting reduced equilibrium and dynamic surface tension by the incorporation of a surface tension reducing amount of an acetylenic diol ethylene oxide/propylene oxide adduct of the structure: where r and t are 1 or 2, (n+m) is 1 to 30 and (p+q) is 1 to 30.Also disclosed is a method for making random and block EO/PO adducts of acetylenic diols by reacting an acetylenic diol with EO and/or PO in the presence of a trialkylamine or Lewis acid.
