  • Acetylenic diol ethylene oxide/propylene oxide adducts and processes for their manufacture
    Patent number: 7348300
    Abstract: Disclosed herein are process solutions, which may be aqueous-based, non-aqueous-based, and combinations thereof, that contain at least one alkoxylated acetylenic diol surfactant. In one aspect, the process solution comprises water and an alkoxylated acetylenic diol surfactant having the formula A: where r and t are 1 or 2, (n+m) is 1 to 30 and (p+q) is 1 to 30.
    Type: Grant
    Filed: February 1, 2005
    Date of Patent: March 25, 2008
    Assignee: Air Products and Chemicals, Inc.

  • Acetylenic diol ethylene oxide/propylene oxide adducts and processes for their manufacture
    Patent number: 6864395
    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.
    Type: Grant

  • Acetylenic diol ethylene oxide/propylene oxide adducts and their use in photoresist developers
    Patent number: 6455234
    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. Use of such adducts as surfactants 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.
