The oligomeric ammonium salts can be used as components in rubber compositions and as anion-active and surface-active substances. Following the method, the reaction is carried out in a solution at a temperature of 60 to 70 degrees C with an available sulphonation agent (ammonium hydrogensulphite). The method ensures high yields and the products can be easily isolated and purified. The salts contain the following main fragments:1. [...-CH2 - CH = CH2 -...]n1, where n1 takes values between 4 and 6.<IMAGE>where n2 takes values between 8 and 12and X' represents NO2, NHSO3NH4, Z'' represents -H, Br.<IMAGE>where n3 takes values between 4 and 6and Z' is H or Br. The salts are prepared with polybromnitrooligomers from butadienestyrene rubber, which are sulphonated with ammonium hydrogensulphite at a ratio of 1/4 to 6, pH of 6.0-7.0, and a temperature of 60 to 70 degrees C for 1.5 to 5.5 hours in a 1,4-dioxan and water solution.
