FIELD: textile fabrics, paper.
SUBSTANCE: method is related to suppression of resin and sticky materials deposits creation in fiber mass in process of paper production and may be used in pulp and paper industry. Method includes stage of multi-stitched cation-active polymer addition into paper liquid mass prior to formation of paper web. This polymer is produced in compliance with the method comprising the following stages: (1) polymerisation of monomer components by free radical initiation with preparation of main cation-active polymer solution, in which at least one of monomer components represents cation-active monomer component such as diallyl dialkyl ammonium monomer; and (11) contact of main cation-active polymer solution with additional initiator of free radical polymerisation with provision of mutually binding connections between main cation-active polymers with provision of multi-stitched cation-active polymer, where this multi-stitched cation-active polymer has higher molecular mass compared to main cation-active polymer.
EFFECT: elimination of anion garbage by fixation of colloidal particles in fiber and suppression of deposits creation by resin and sticky materials.
