Cationic starch adsorption onto cellulosic pulp in the presence of other cationic synthetic additives.

Highlights: [•] Synthetic polycations interfere with cationic starches at adsorption onto fiber. [•] The addition of synthetic polycations after cationic starch results in higher adsorption amounts. [•] The replacement of cationic starch depends on molecular properties of the starch itself and of the synthetic polycation. [Copyright &y& Elsevier]
