Patent

CA 2261960

This invention relates to resins useful for imparting dry-strength and temporary wet-strength to paper, the process of incorporating these resins into paper and the paper produced containing the resins. The resin comprises an amphoteric polymer produced through polymerization of an anionic monomer, a monomer containing aldehyde functionality and a cationic monomer.

Cette invention a trait à des résines utilisées aux fins de conférer une résistance à l'état sec et une résistance à l'état humide temporaire au papier; au procédé d'incorporation de ces résines dans le papier; ainsi qu'au papier produit et contenant ces résines. Cette résine contient un polymère amphotère produit grâce à la polymérisation d'un monomère anionique, d'un monomère contenant une fonction aldéhyde et d'un monomère cationique.
