ABSTRACT:
Water-dispersible, storage-stable pulverulent compositions of matter, well adopted as adjuvants for hydraulic binders used in the construction industry, comprise particulates of a water-insoluble film-forming vinyl and/or acrylic polymer, e.g., a vinyl ester, alkyl(meth)acrylate or vinylaromatic homopolymer or copolymer, containing from 0.5 to 20 parts by weight of at least one silicone, e.g., an alkali or alkaline earth metal organosiliconate or a liquid organopolysiloxane, per 100 parts by weight of such film-forming polymer.
