摘要：

The soda-additive pulps of pine wood were compared to corresponding soda and kraft pulps in respect to the macromolecular properties of the residual pulp lignins. Results of measurements of number and weight-average molecular weights as well as branching parameters show that the presence of additives such as anthraquinone, methanol and O2-pretreatment significantly causes the breaking of cross-links in the pulp lignin. On the other hand, ethylenediamine and hydrosulfide ion contribute mainly to extensive lignin degradation. The influence of used additives on the condensation reactions of the residual lignin has also been studied.
