主权项 1. A dry self-suspending proppant comprising a proppant particle substrate and a coating on the proppant particle substrate, wherein the coating comprises the reaction product obtained when a hydrogel-forming polymer is crosslinked by means of a covalent crosslinking agent in the presence of an organofunctional compound comprising one or more polyols, one or more polyamines or a mixture thereof, wherein the covalent crosslinking agent is also capable of reacting with the organofunctional compound.
