Patent ID: 7686884

Claim:
A hydraulically setting composition, characterized in that it contains esters or ester salts, comprising alkoxy groups, of phosphorus-oxygen acids of the general formula (I), (II), (III) or (IV) R 3 —NR 4 k —[(CH 2 ) n —PO(OR 1 )(OR 2 )] m (I) [(R 1 O)(R 2 O)OP—(CH 2 ) n —] m —NR 4 k —R 5 —NR 4 k —[—(CH 2 ) n —PO(OR 1 )(OR 2 )] m (II) R 3 —NR 4 k —[(CH 2 ) n —PO(OR 1 )(OM)] m (III) [(MO)(R 1 O)OP—(CH 2 ) n —] m —NR 4 k —R 5 —NR 4 k —[—(CH 2 ) n —PO(OR 1 )(OM)] m (IV) where n is an integer from 0 to 10, m+k is 2 and m is 1 or 2 and k is 0 or 1, at least one of the radicals R 1 , R 2 and optionally R 3 is an alkoxy group of the general formula —[CH 2 —CHR 6 —O] 1 R 7 , where 1 is from 2 to 30 and R 6 and R 7 are each H or CH 3 , and the radicals R 1 and R 2 , where they are not alkoxy groups, are straight-chain or branched, optionally substituted C 1 - to C 6 -alkyl groups, and R 3 , where it is not an alkoxy group, is a straight-chain or branched, optionally substituted, C 1 - to C 20 -alkyl group or aryl group, R 4 is H or a straight-chain or branched, optionally substituted C 1 - to C 6 -alkyl group, R 5 is a divalent, bridging group, and M is at least one cation selected from the group consisting of alkali metal, alkaline earth metal or ammonium ions.
