Polymers obtained by radical polymerization and containing (A) from 0.1 to 80 mole percent of polymerized units corresponding to the following formula ##STR1## in which R.sub.1 represents hydrogen or methyl, R.sub.2 represents alkyl, particularly primary or secondary alkyl containing from 1 to 4 carbon atoms, and R.sub.3 represents hydrogen or alkyl, particularly primary or secondary alkyl containing from 1 to 4 carbon atoms, and in which the sulphonic acid group may be present in the form of a salt, and (B) from 20 to 99.9 mole percent of polymerized units of one or more ethylenically unsaturated monomers, are particularly suitable for the production of filaments, fibres and films having a high absorption capacity for basic dyes.
