ADDITIVE COMPATIBLE WITH CLAY FOR CHEMICALS APPLICABLE IN CONSTRUCTION INDUSTRY Russian patent published in 2017 - IPC C08G2/20 C08G4/00 C08G14/00 C04B24/30 C04B28/00 C08L61/00 C08L61/34 

FIELD: chemistry.

SUBSTANCE: condensation product based on monomers. The monomers include: I) at least, one monomer having an aldehyde moiety; and II) at least, one monomer having a ketone moiety that carries, at least, one non-aromatic moiety, and wherein the condensation product comprises, at least, one moiety from the series of phosphono, sulfino, sulfo, sulfamido, sulfoxy, sulfoalkyloxy, sulfinoalkyloxy and phosphonooxy and/or their salts, the product is characterized in that the monomers further contain III) gallic acid. In addition, the manufacture and use of these condensation products in chemical products for the construction industry are disclosed.

EFFECT: product, when used in building materials, provides only a slight colour change on the surface of solidified products, provides better compatibility with clays.
