Abstract

Polymers containing .beta.-hydroxyalkylvinylamine units, which are obtainable by reacting polymers containing vinylamine units with epoxides of the formula ##STR1## where R=C.sub.2 -C.sub.28 -alkyl, phenyl, C.sub.1 -C.sub.18 -alkylphenyl or C.sub.2 -C.sub.18 -alkenyl, are described, as are a process for preparing the polymers and use of the polymers as retention and drainage aids and flocculants and as fixatives in paper making, as protective colloid for producing alkyldiketene dispersions or alkenylsuccinic anhydride dispersions, as emulsifier for producing aqueous filler suspensions and as corrosion inhibitor.
