Способ получения мочевиноформальдегидных смол ступенчатой конденсацией мочевины с формальдегидом в присутствии модифицирующего агента в средах с переменной кислотностью при нагревании, отличается тем, что в качестве модифицирующего агента используют моноэтаноламин в количестве 0,01-0,02 молей на 1 моль мочевины до конечного мольного соотношения мочевины к формальдегиду 1:1,0-1,2 соответственно.The method of producing urea-formaldehyde resins by stepwise condensation of urea with formaldehyde in the presence of a modifying agent in media with variable acidity when heated differs in that monoethanolamine is used as a modifying agent in an amount of 0.01-0.02 moles per 1 mol of urea to a final molar ratio of urea to formaldehyde 1: 1.0-1.2, respectively.
