Polymers containing .beta.-hydroxyalkylvinylamine units, which are obtainable by reacting polymers containing vinylamine units with epoxides of the formula (see formula I) where R = C2-C28-alkyl, phenyl, C1-C18-alkylphenyl or C2-C18-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.
L'invention concerne des polymérisats contenant des unités beta -hydroxyalkylvinylamine, obtenus par réaction de polymérisats contenant des unités vinylamine avec des résines époxy de la formule (IV), dans laquelle R = alkyle C2-C28, phényle, alkyle C1-C18-phényle ou alcényle C2-C18. L'invention concerne en outre un procédé de préparation de ces polymérisats et leur utilisation comme agents de rétention, de déshydratation et de floculation, ainsi que comme agents de fixation dans la fabrication du papier, comme colloïde protecteur pour produire des dispersions de dicétène d'alkyle ou des dispersions d'anhydride d'acide alcényl succinique, comme émulsifiant pour produire des boues de charge aqueuses et comme inhibiteur de corrosion.
