The Dry Strength Additives are polymer of acrylamide & are anionic, cationic and amphoteric in nature, It mainly helps to increase the strength properties, surface properties, better formation & degree of stiffness (rattling) of paper and also helps in strengthening per unit of bonded area between fibers, maintaining higher dewatering rates, lower density of paper & better machine runnability with increased machine speed.
