Patent

CA 2573242

The present invention relates to embodiments of a process for making polyalkyldiallylamine-epihalohydrin resins, the resultant resins and their uses as wet strength additives for papermaking. These resins are obtained by a process, wherein the salt of an alkyldiallylamine monomer is copolymerized and further reacted with epihalohydrin under carefully controlled reaction conditions.

La présente invention se réfère à des réalisations d'un procédé pour réaliser des résines polyalkyldiallylamine-épihalohydrine, les résines en résultant et leur utilisation comme agents permettant la résistance du papier à l'état humide dans la fabrication. Ces résines sont obtenues par un procédé où le sel d'un monomère d'alkyl diallylamine est copolymérisé et est ensuite amené en réaction avec l'épihalohydrine dans des conditions de réaction contrôlées avec précaution.
