Fig. 1From: Assessing rheometry for measuring the viscosity-average degree of polymerisation of cellulose in paper degradation studiesDynamic viscosity as a function of the shear rate as measured by rotational rheometry for a Specimen 1—artificially aged for 6 days, and b Specimen 2—artificially aged for 35 days. The measurement region used for determining the dynamic viscosity is indicated by means of red solid circlesBack to article page
