ABSTRACT:
Particles of water soluble polymers such as poly(olefin oxides) are formulated to readily dissolve without agglomerating by associating polymer particles with particles of gas producing compounds, suitably a bicarbonate and an acid salt, which are non-reactive to the polymer but produce gas when wetted with water whereby the generated gas maintains polymer particles in separation as the particles dissolve.
