The instant invention relates to certain cross-linked polyamides and their use in the paper and board industry for improving dry strength. The polyamide from the reaction of a di- or tri-primary amine with a di- or tri- or tetra carboxylic acid is further reacted with a di- or tri-functional cross-linking compound to give a cationic or anionic product with no reactive groups.

La présente invention concerne certains polyamides réticulés et leur utilisation dans la fabrication du papier et du carton afin d~améliorer la résistance à sec. Le polyamide issu de la réaction entre une di- ou triamine primaire avec un acide di-, tri- ou tétracarboxylique est mis en réaction avec un composé réticulant di- ou trifonctionnel afin d~obtenir un produit anionique ou cationique ne comportant pas de groupements réactifs.
