Résumé: This article presents the impact of a degree of polymerization on the papermaking potential of paper. Bleached pinewood kraft pulp from one of paper mills was used for research purposes. The main objective of this work was to investigate the influence of a degree of polymerisation of pulp on the properties of fibres such as water retention value (WRV) and the fines content etc. Different degrees of polymerization were obtained as a result of the pulp drying at different temperatures (105˚C, 130˚C and 150˚C) for a period from 1 hour up to 150 hours. During the drying process, a visible decrease in a degree of polymerization of cellulose in hornified fibres occurs. Significant differences in pulp properties can be observed in particular in case of pulps dried at a very high temperature (150°C) and in case of a long drying time (150 h).
