FIELD: chemistry.
SUBSTANCE: cross-linkable composition contains a water-based liquid, a buffer pH regulator, a cross-linkable organic polymer, a cross-linking agent and a retardant. The cross-linking agent is selected from a group comprising an organic titanate, an organic zirconate or combination thereof. The retardant is hydroxyalkylaminocarboxylic acid. The cross-linkable organic polymer is selected from a group comprising soluble polysaccharides, polyacrylamides and polymethacrylamides.
EFFECT: cross-linkable composition enables to control the rate of cross-linking and can be used in a wide pH range, in a range of different cross-linking rates using the same composition.
