Abstract: AKD cellulosic composition obtainable by flowing a stream of a cellulosic suspension through a shearing device and in which a molten alkyl ketene dimer (AKD) is metered in to the stream of cellulosic suspension in or prior to the shearing device. The AKD cellulosic composition is particularly suitable in the manufacture of sized paper and paperboard.
