FIELD: chemistry.
SUBSTANCE: method for removing solvent from polymer solution, which contains, at least, one elastomer polymer, includes carrying out stage of distillation for said polymer solution by means of water steam in presence of dispersing system, which contains: at least, one lamellar substance, content of which constitutes from 0.005 wt % to 1 wt % relative to the total weight of dry elastomer polymer, with thickness of lamellae of said lamellar substance being in the range from 0.01 nm to 30 nm, and lamellar substance is selected from phyllosilicates, such as given in the invention formula, and, at least, one cationic surface-active substance, content of which constitutes from 0.0005 wt % to 1 wt % relative to the total weight of dry elastomer polymer.
EFFECT: application of reduced quantity of additives to obtain polymer of sufficient quality.
