APPLICATION OF COMB-LIKE POLYMERS AS SEDIMENT INHIBITORS IN PRODUCTION OF CELLULOSE BY SULFATE METHOD (KRAFT PROCESS) Russian patent published in 2021 - IPC D21C3/02 D21C3/22 D21C9/02 

FIELD: polymers.

SUBSTANCE: invention relates to the use of comb-like polymers, which can be obtained by radical polymerization of monoethylene-unsaturated monomers from Group A1) monoethylene-unsaturated acids and their salts and Group A2) monoethylene-unsaturated polyesters, as a sediment inhibitor in the production of cellulose by the sulfate method (kraft process).

EFFECT: use of comb-like polymers as a sediment inhibitor in the production of cellulose by the sulfate method (kraft process) is proposed.
