摘要：

Triblock functional copolymer, containing ethylene oxide and ethyleneimine blocks, were synthesized by tosylation of the terminal hydroxyl groups of poly(ethyleneglycol). The tosylated prepolymer was used as initiator for the cationic polymerization of 2-methyl-2-oxazoline producing a triblock copolymer. Finally, by basic hydrolysis the N-acetyl groups were transformed into secondary amino groups that are chemically reactives. The copolymer structures were analyzed by FT-IR, H-1-NMR and C-13-NMR spectroscopy.
