Abstract: High resolution NMRspectra of several kinds of Polysulfone-Polyesters(PSF-PPT, PSF-PBT, PSF-PHT, PSF-PDET, PSF-PTET) block copolymers were measured.The composition and sequence distribution of Polysulfonc-Polyesters block copolymers were studied. Proton signals due to helerolinkages could be observed in these block copolymers, and the average sequence length (L) and the degree of Randomness (B) in the Polysulfone-Polyesters block copolymers were calculated from the intensities of their signals.Bof block copolymers lie in the region of 0<B<1.
