METHOD OF PREVENTING AND REDUCING ALUMINOSILICATE DEPOSITS IN INDUSTRIAL PROCESSES Russian patent published in 2011 - IPC C08F8/00 C08F230/08 C23F14/02 

FIELD: chemistry.

SUBSTANCE: invention discloses versions of polymers and a method in which polymers which contain at least 5 mol % groups in a side chain, containing -Si(OR")₃ (where R" is H, C₁-C₃ alkyl, aryl, Na, K or NH₄) or at last 5 mol % terminal group containing Si(OR")₃ (where R" is Na, K or NH₄), are used to regulate aluminosilicate deposits in an industrial process with an alkaline process flow, such as flow in sulphate-cellulose production.

EFFECT: when disclosed substances are added to a process flow in economically acceptable concentrations, said substances reduce or even completely prevent formation of aluminosilicate deposits on the surface of equipment.
