Abstract

Selon un procédé de modification cationique d'amidon, on fait réagir l'amidon avec des polymères qui contiennent des groupes amino et/ou ammonium dans un milieu aqueux à des températures comprises entre 115 et 180 DEG C sous une pression accrue, en l'absence d'oxydants, d'initiateurs de la polymérisation, et d'alcali. On conduit la réaction de sorte qu'au maximum 10% en poids de l'amidon subisse une réduction de son poids molaire. L'invention concerne également l'utilisation des produits de réaction ainsi obtenus comme agents de résistance à l'état sec du papier.
