Beschreibung
Zusammenfassung:	This invention relates to resins useful for imparting strength to paper, the process of incorporating these resins into paper and the paper produced containing the resins. In particular the invention relates to resins useful for imparting dry-strength and wet-strength to paper under conditions of high sulfite ion concentrations. Cette invention a pour objet des résines utilisées pour conférer une certaine résistance au papier, le processus d'incorporation de ces résines dans du papier, et le papier ainsi produit renfermant les résines. Notamment, ladite invention a trait aux résines utilisées pour conférer des résistances au mouillé et au sec au papier dans des conditions de concentrations élevées d'ions de sulfite.
