Patent

CA 2469039

Paper webs treated with a polyvinylamine polymer and a second agent that interacts with the polyvinylamine polymer is disclosed. The second agent added with the polyvinylamine polymer can be, for instance, a polymeric anionic reactive compound or a polymeric aldehyde-functional compound. When incorporated into a paper web, the combination of the polyvinylamine polymer and the second agent provide improved strength properties, such as wet strength properties.

L'invention concerne des bandes de papier traitées avec un polymère polyvinylamine et un second agent produisant une interaction avec le polymère polyvinylamine. Ce second agent ajouté conjointement au polymère de polyvinylamine peut être par exemple un composé réactif anionique polymère ou un composé polymère à fonction aldéhyde. Lorsqu'elle est incorporée à une bande de papier, cette combinaison de polymère polyvinylamine et du second agent permet de donner à la bande de papier des caractéristiques de résistance améliorées, telles qu'une résistance améliorée à l'état humide.
