Sa. Pooley et al., COPOLYMERIZATION VIA ZWITTERION OF N-(2-HYDROXYETHYL)ETHYLENEIMINE WITH PHTHALIC-ANHYDRIDE, Boletin de la Sociedad Chilena de Quimica, 39(4), 1994, pp. 305-313
The copolymerization of N-(2-hydroxyethyl)ethyleneimine as nucleophili
c monomer and phtalic anhydride as electrophilic monomer without initi
ator in solution under different mole ratios was investigated. The cop
olymers were characterized by elemental analyses, IR and H-1-NMR spect
roscopy. The thermal stability of the copolymers was studied. From the
copolymer compositions, FT-IR and H-1-NMR spectra, it was possible to
suggest a copolymer structure.
