Abstract
The invention relates to synthetic polymers obtainable by condensing PA1 A. a carboxyl-group-bearing polymer having a molecular weight of between 300 and 10,000, PA1 B. a primary aliphatic amine containing 1 to 6, preferably 1 to 3, particularly 1, hydroxyl group, PA1 C. an epihalohydrin, and PA1 D. an alkyl(C.sub.11 -C.sub.22) or alkenyl(C.sub.11 -C.sub.22) group-containing mono or poly amine, unsubstituted or substituted on the alkyl or alkenyl chain by hydroxyl and/or substituted on the amino function(s) by alkyl(C.sub.1 -C.sub.3), unsubstituted or substituted by hydroxyl and/or a group EQU (--CH(Ro)--CH.sub.2 --O).sub.r --H EQU or (--CH.sub.2 --CH(Ro)--O)--O).sub.r H PA1 wherein Ro is hydrogen, methyl or ethyl, and r is an integer 2 to 30, that are water dispersible and in disperse form are useful as wash softeners for synthetic fibers especially polyamide fibers.
