FIELD: chemistry. ^ SUBSTANCE: method involves reacting derivative of maleic anhydride with n-aminodiphenylamine while heating to temperature not above 90C. The derivative of maleic anhydride used is alkenyl succinic anhydride or a mixture of alkenyl succinic anhydrides of general formula: , where n=6,8,10,12,14,16,18 with molar ratio of maleic anhydride links to n-aminodiphenylamine equal to 1.0-1.05:1.0. ^ EFFECT: improved processing characteristics of antioxidant, characterised by low dropping point, high efficiency for emulsion-polymerised rubber and latex, protection of said rubber from thermal-oxidative ageing. ^ 1 tbl, 7 ex |
