Novel derivatives of phosphonalcane polycarboxylic acids and use thereof

Use, as an agent for crosslinking cellulose, of derivatives of alkanepolycarboxylic acids corresponding to the general formula I: in which: - n, m = 0 or 1, - R1, R3, R5 and R7 = H or COOH it being understood that at least two substituents among the said substituents R1, R3, R5 and R7 denote a c...

Beschreibung
Zusammenfassung:	Use, as an agent for crosslinking cellulose, of derivatives of alkanepolycarboxylic acids corresponding to the general formula I: in which: - n, m = 0 or 1, - R1, R3, R5 and R7 = H or COOH it being understood that at least two substituents among the said substituents R1, R3, R5 and R7 denote a carboxy group, - R2, R4, R6 and R8 = H or PO(OH)(OR) where R = H or C1-C4 Alk, it being understood that only a single substituent among the said substituents R2, R4, R6 and R8 denotes the said group PO(OH)OR, textile finishes containing the said products of formula I, new derivatives of formula I and process for their preparation.
