Two commercial ligninsulphonate samples have been investigated by means of gel permeation chromatography (GPC), viscosity, potentiometric titration and conductivity measurements. The molecular-weight distributions given by GPC showed that the two samples consisted of a large portion of high molecular weight materials (¯w > 50 000), and a small part of low molecular weight (¯w ≃ 5000). The results obtained from titration yielded a sodium content of about 6% for both samples, and these results… CONTINUE READING
