Sa. Pooley et al., COPOLYMERIZATION WITHOUT INITIATOR OF N-(2-HYDROXYETHYL)ETHYLENEIMINEWITH SUCCINIC ANHYDRIDE, Polymer bulletin, 35(3), 1995, pp. 271-277
Copolymers of N-(2-hydroxyethyl) ethyleneimine and succinic anhydride
without initiator were prepared under different experimental condition
s. The composition of the copolymers was determined by elemental analy
ses and H-1-NMR spectroscopy. From the results of FT-IR and H-1-NMR sp
ectroscopy a scheme of copolymerization via zwitterion is presented wh
ich includes an esterification reaction of the pendant hydroxylic grou
