Claim:
A composition comprising: (a) at least one substituted or unsubstituted polyalkylene glycol of the formula (I): R 11 —O—(R 12 —O) x —(R 13 —O) y —R 14 (I) in which: R 11 is H or C 1 - to C 20 -alkyl, R 12 is C 2 - to C 4 -alkylene, R 13 is C 2 - to C 4 -alkylene, R 14 is H or C 1 - to C 20 -alkyl, x is 0-500, y is 0-500, and x+y is >20; and (b) at least one plasticizer for a hydraulically setting composition, the plasticizer comprising at least one polymer A of formula (II): in which: M, independently of one another, is H + , alkali metal ion, alkaline earth metal ion, divalent or trivalent metal ion, ammonium ion or organic ammonium group, R, each R independently of the other, is hydrogen or methyl, R 1 is -[AO] n —R 4 , where n is selected so that a molecular weight of R 1 is not greater than 3000 g/mol, A is C 2 - to C 4 -alkylene, and R 4 is C 1 - to C 20 -alkyl, cyclohexyl or alkylaryl, R 2 is C 1 - to C 20 -alkyl, cycloalkyl, alkylaryl or -[AO] n —R 4 , in which: A is C 2 - to C 4 -alkylene, R 4 is C 1 - to C 20 -alkyl, cyclohexyl or alkylaryl, and n is 2-250, R 3 is —NH 2 , —NR 5 R 6 , —OR 7 NR 8 R 9 , in which R 5 and R 6 , independently of one another, are: H or a C 1 - to C 20 -alkyl, cycloalkyl or alkylaryl or aryl group; or is a hydroxyalkyl group, or is an acetoxyethyl (CH 3 —CO—O—CH 2 —CH 2 —) or a hydroxyisopropyl (HO—CH(CH 3 )—CH 2 —) or an acetoxyisopropyl group (CH 3 —CO—O—CH(CH 3 )—CH 2 —), or R 5 and R 6 together form a ring, of which the nitrogen of the —NR 5 R 6 is a part in order to build up a morpholine or imidazoline ring, in which R 7 is a C 2 -C 4 -alkylene group, and R 8 and R 9 , independently of one another, are a C 1 - to C 20 -alkyl, cycloalkyl, alkylaryl, aryl or hydroxyalkyl group, a, b, c and d are molar ratios, a/b/c/d is (0.05-0.9)/(0.05-0.95)/(0-0.8)/(0-0.5), and a+b+c+d=1; wherein: a proportion of the polyalkylene glycol is from 1 to 45% by weight based on a total dry weight of the composition; a proportion of the at least one plasticizer is from 50 to 95% by weight based on the total dry weight of the composition; and a molecular weight M w of the polyalkylene glycol is from 4,000 to 20,000 g/mol.
