Resumen

This paper presents the effect of the structure of cationic polyacrylamides (CPAMs) on flocculation of pulp
suspensions and floc properties. A focused beam reflectance measurement (FBRM) probe was used to monitor
flocculation, deflocculation, and reflocculation processes in real time. To carry out the study, 1% elemental
chlorine free (ECF) eucalyptus kraft pulp containing 20% ground calcium carbonate (GCC) was used. Results
show that the effect of the CPAM structure depends on charge density and polymer dose. Floc size does not
always decrease with branching degree, whereas floc stability and reflocculation ability increased when highly
charged and branched CPAM was used. These findings indicate that the use of highly branched CPAMs with
very high molecular weight is very promising as a retention aid method to improve the papermaking process.
