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

- 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.
