Specific functionalization of polyoxirane by amino, carboxyl, sulfo, and halogeno end groups

Abstract

Abstract Polyoxiranes with amino, carboxyl, or halogeno end groups were prepared by polymerization of oxirane with either anionic initiators substituted with functional or protected functional groups, or by reaction of functional deactivating reagents with anionically prepared polyoxiranes. For the protection of primary amino groups they were transformed into the corresponding cyclic imido derivatives. The deactivation of polyoxirane with potassium oxido end groups by bis(halogenomethyl)benzenes was studied with the three isomers.
