1470243 Polyethers containing aziridine radicals BASF AG 5 July 1974 [7 July 1973] 29879/74 Heading C2C [Also in Divisions C3 and D1] A compound containing aziridine radicals has the formula in which RSP1/SP to RSP7/SP are the same or different and are H or C 1-4 alkyl; Q is the radical after removal of n hydrogen atoms from the hydroxyl groups of an n-hydrie alcohol or phenol; n is 2 or 3 and X is a polyether chain of oxybutylene and/or oxypropylene units and optionally oxyethylene units, said chain having a C : O atomic ratio of #2À67 : 1 and M.W. of 150-1500 if n=2 and 15-3000 if n = 3. I may be prepared by transesterification of a polyether Q(XH) n with a #-aziridinocarboxylic ester in which R is C 1-4 alkyl.
