FIELD: chemical industry. SUBSTANCE: claimed process relates to processes for preparation of stabilizers for polymeric materials and rubbers. Method involves reacting respective 2,6-dialkyl(cycloalkyl, aralkyl or aryl) phenol, N,N-tertaalkylmethylene-bis-amine and hydrogen sulfide in equimolar amounts and carrying out process in admixture of two aprotic and proton-donor solvents at volumetric ratio of 99:1 to 1:99. EFFECT: simplified process technology, increased yield of product and improved ecological properties. 2 cl |
