The most widely used synthetic additives to improve drainage and fines retention during the formation of the fibrous mat are cationic polymers. These polymers are also frequently used to improve paper wet strength and internal bonding.(¹) Their wide applicability is based on their preferential adsorption onto the anionic fibres and fines.
