FIELD: production of filter materials on base of three-dimensional globular polymers; water filtration systems.
SUBSTANCE: proposed method includes poly-condensation of carbamide and aldehyde in presence of acid and forming of resin at cooling and holding till complete hardening; furfural is used as aldehyde; poly-condensation is carried out at heating till dynamic viscosity of solution gets equal to 40-50 mPs; cooling is performed at rate making it possible to obtain material at average diameter of pores of 1-4 mcm.
EFFECT: enhanced efficiency; possibility of producing pure material.
