Abstract

A gellable aqueous composition, having a retarded gelling time, capable of producing gel which is resistant to syneresis in the presence of divalent ions, contains: - a water-soluble acrylamide polymer, - a water-soluble aldehyde and phenol as cross-linking agents, and - malonic acid, as an agent retarding gelling and preventing syneresis.
