The current study proposes an efficient, alternative method to evaluate DP v of cellulosic paper, which is based on rotational rheometry. DP v can be deduced from the viscosity of dilute paper solutions, as typically measured through glass capillary viscometry. In paper degradation studies, the viscosity-average degree of polymerisation (DP v) is often used as a key indicator of the extent of degradation of cellulosic paper.
