FIELD: chemistry.
SUBSTANCE: present invention relates to compositions of aldehyde-functionalised polymers, which are stabilised with inorganic salts, organic additives or combinations thereof, and to a method of prolonging the shelf life of the composition. Stabilising additives can be added to aldehyde-functionalised polymers until a stabilised aldehyde-functionalised polymer composition is formed at any stage of the functionalisation reaction. The composition contains one or more aldehyde-functionalised polymers with weight-average molecular weight of at least about 50000 g/mol. At least one stabilising additive contains as an inorganic salt alkali or alkali-earth metal salts, hydrates thereof and any combination thereof. The used organic additive can be diols, triols, polyols, glycerine, ethylene glycol, saccharides, urea and any combination thereof.
EFFECT: described is a method of producing a material having cellulose fibres, and use of the composition for producing cellulose fibre products in the papermaking process.
