Use of a copolymer as an adjuvant for hydraulic binder, which is useful to prepare elements for construction field e.g. chemical industry, and as fluidizing and/or blocking agent, where copolymer comprises ester and ketone units
Use of at least one copolymer or one of its salts as an adjuvant for hydraulic binder, where the copolymer comprises an ester unit (I) and at least a ketone unit (II) and the molar mass of the copolymer is 500-20000 Daltons, is claimed. Use of at least one copolymer or one of its salts as an adjuvant for hydraulic binder, where the copolymer comprises at an ester unit of formula (I) (-C(R 2)(R 3)-C(R 1)(C(=O)-OR 4)-) (I) and at least a ketone unit of formula (-C(R 6)(R 7)-C(R 5)((CH 2) n-C(=O) m-W 1-(R 8-O) q-R 9)-) (II), and the molar mass of the copolymer is 500-20000 Daltons, is claimed. R 1-R 3H (preferred), 1-20C alkyl, -(CH 2) p-COOR or ionized form; p : 0 or 1; R : H or 1-6C alkyl; R 4H, monovalent, divalent or trivalent ion or quaternary ammonium radical; R 5-R 7H (preferred), 1-20C alkyl or (-(CH 2) n-(C=O) m-W 1-(R 8-O) q-R 9); R 82-20C, preferably 2C alkyl radical; R 9H (preferred), or 1-20C, preferably 1C alkyl; W 1O (preferred) or N; n : 0-2; m : 0-1; and q : 0-200, preferably 4-25. Independent claims are included for: (1) a hydraulic binder comprising the copolymer; and (2) an element for the construction field obtained from hydraulic binder comprising the copolymer.
