Abstract

Acetal-protected and sulfonamide-activated aziridines (Az) have been prepared and polymerized by living anionic polymerization with molecular weight dispersities in most cases below < 1.2 and controlled molecular weights. Three new monomers have been prepared varying in the length of the pendant chain. The resulting double protected polymers can be selectively deprotected in order to release the polyamine or the polyol structures. Detailed structural characterization was performed for all polymers, and chain extension proves their living polymerization behavior and the formation of block copolymers. Thermal analysis can be used in order to follow the deprotection steps. These new protected monomers broaden the scope of the azaanionic polymerization of aziridines and may find useful applications as well-defined functional poly(ethylene imine) derivatives.
