Abstract
Diallylamine compounds may be polymerized to water-soluble, linear, high-molecular weight polymers having low residual monomer content by the use of cationic azo initiators and phosphorous acid or a derivative thereof as regulator. The polymers are useful as pre- or after-treatment agents for anionic dyeings on textile substrates.
