COPOLYMERIZATION WITHOUT INITIATOR OF AZIRIDINE WITH SUCCINIC ANHYDRIDE

The copolymerization of aziridine (Az) as nucleophilic monomer and suc cinic anhydride as electrophilic monomer without initiator in solution under different mol ratio was investigated. Copolymers were character ized by elemental analyses, i.r. and H-1-NMR spectroscopy. For all fee d mole ratio of comonomer, Az is incorporated preferentially in the co polymer. For the soluble copolymers it is possible by H-1-NMR spectros copy to determine the Az-homodyad concentration. The copolymerization reaction occurs by an intermediate ''genetic zwitterion''.
