Abstract
The present invention contains a process for manufacturing a water-soluble, self-crosslinking, polymeric condensation product by reacting 1 mole di-C.sub.1-4 -alkylamino-C.sub.24 alkyl(meth)acrylates with 0.3 to 1.5 mol di-C.sub.1-3 -alkyl-phosphonates in the presence of water under heating up to a remarkable increase of the viscosity. If aqueous solutions of these condensation products are used for the treatment of fibrous materials, a very high antistatic effect is imparted to them with only small changes of shade and a very good dry- and wet rubbing fastness as well as water-fastness. The effects show a good permanency.
