Abstract

Oppfinnelsen vedrører blandinger inneholdende hovedsakelig amorfe cellulosenanofibriller, karboksycellulose med en substitusjonsgrad på ikke mer enn 0,95 som additiv, og eventuelt minst ett ko-additiv, idet innholdet av additiv og av eventuelt ko-additiv er mindre enn 30 vekt% i forhold til vekten av nanofibriller og additiv og eventuelt ko-additiv. Oppfinnelsen vedrører også en fremgangsmåte for fremstilling av slike blandinger som består i tilsetning til en hoved- sakelig amorf nanofibrillsuspensjon av additivet og eventuelt ko-additivet eller ko-additivene, og deretter tørking av den således supplerte suspensjon. De resulterende blandinger er lett redispergerbare og bevarer alle deres reologiske egen- skaper.
