Abstract
A method of rapidly dissolving particles of water soluble polymer gels in water. A suspension of gel particles is formed and subjected to conditions of high shear in a particle size reduction apparatus whereby finely sliced particles are formed and instantly dissolve in water. Sufficient water is present that heat is dissipated and molecular degradation of the polymer is avoided.
