Zwitterion copolymerization of N ‐ tert ‐butylaziridine (TBA) with the weak π‐electron acceptor maleic anhydride (MA) was investigated. It was demonstrated that the reaction proceeds by opening of both aziridine and anhydride rings, and copoly(ester‐amide)s of different composition were prepared depending on the polymerization conditions. On the basis of a model reaction it was assumed that charge‐transfer interaction is a stage of the zwitterion mechanism. The structure and the composition of the products obtained were investigated.
