Zusammenfassung:N-Sulphonylaziridines of formula (I): (where R1 = aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic gp.; R2 and R3 = H or aliphatic gp.; n = 1-5) are prepd. by reacting R1(SO2X)n (II) (X = halo) with an R2,R3-substd. aziridine (III) at ratio 1.5 wt equivalents (III) per wt. equivalent (II) opt. in the presence of = 0.1 wt. equivalent of an additional base per wt. equivalent (II). (I) are used to make additives for paper, leather and textiles and textiles e.g. antistatics, fire retardants or high quality sizes and in prodn. of synthetic waxes and pesticides.
