Abstract
Dialkylphosphonopropionic acid amides of formula ##STR1## WHEREIN R is a straight-chain or branched alkyl radical of 1 to 8 carbon atoms, R.sub.1 is hydrogen or methyl, R.sub.2 is hydrogen or C.sub.n H.sub.2n.sub.+1 and n is an integer from 1 to 24, are provided. These compounds are useful for finishing synthetic organic fibrous material, in particular for providing it with an antistatic finish and optionally for simultaneously improving the dirt repellency, when applied in admixture with further monomeric compounds or with polymers; said compounds or mixtures are applied to the fibrous material from aqueous or organic preparations and the fibrous material is subsequently dried at elevated temperature.
