This paper describes the synthesis of new model compounds and copolyether s
ulphones with different reactive chain-ends from the OH and NH2 ends which
are well documented for this type of polymer. These materials were characte
rised by H-1 NMR, Fourier transformed infrared (FTIR) spectroscopy and elem
ental analysis. They are seen to have potential applications both in the ch
ain-extension of low molecular weight thermoplastics and in the preparation
of well-defined block copolymers. (C) 1999 Elsevier Science Ltd. All right
