Beschreibung
Zusammenfassung:	The invention relates to a composition for use in a manufacture of paper, board or the like. The composition comprises a mixture of cationic starch having amylopectin content of at least 85 %, and an amphoteric polymeric structure comprising structural units originating from non-ionic monomers, preferably (meth)acrylamide, anionic groups and cationic groups, the polymeric structure comprising cationic groups at least 0.2 mol-%. L'invention concerne une composition destinée à être utilisée dans une fabrication de papier, de carton ou analogue. La composition comprend un mélange d'amidon cationique dont la teneur en amylopectine est d'au moins 85 %, et une structure polymère amphotère comprenant des unités structurelles provenant de monomères non ioniques, de préférence du (méth)acrylamide, de groupes anioniques et de groupes cationiques, la structure polymère comprenant des groupes cationiques à raison d'au moins 0,2 % en moles.
