surfactant free alkaline swellable acrylic emulsions, their use in aqueous formulations and formulations containing them

摘要

surfactant free alkaline swellable acrylic emulsions, their use in aqueous formulations and formulations containing them. The present invention relates to novel non-water-soluble, thickener-free swellable thickening alkaline emulsions: as a result, all disadvantages related to the use of solvents or foaming in the case of surfactants are avoided. These new emulsions contain a certain amount of 2-acrylamido-2-methylpropane sulfonic acid (or amps, cas #: 40623-75-7). they have proven effective in thickening aqueous media, particularly water-based inks, paper coatings, aqueous suspensions of mineral materials, detergents, cosmetic formulations, or formulations containing a hydraulic binder.
