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. Use of such adducts as surfactant in photoresist developer/electronics cleaning compositions is particularly advantageous.
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.
本发明提供的
水基组合物,尤其是涂料、墨
水、润发液和农用组合物,通过加入表面张力降低量的结构为
乙炔二醇
环氧乙烷/环氧
丙烷加合物,可降低平衡表面张力和动态表面张力。
其中 r 和 t 为 1 或 2,(n + m) 为 1 至 30,(p + q) 为 1 至 30。在光阻显影剂/电子清洗组合物中使用此类加合物作为表面活性剂尤其有利。
本发明还公开了一种制造
乙炔二醇的无规和嵌段
EO/PO 加合物的方法,该方法是在
三烷基胺或
路易斯酸存在下,使
乙炔二醇与
EO 和/或 PO 反应。
