摘要

Synthesis and characterization of a series of Polysulfone (PSF)-Polyester (PEs) block copolymers were studied.The degree of randomness (B) of these block eopolymers was calculated from the intensities of their proton signals in 1H NMR spectra and lies in the region of 0BB)and the average sequence length(L)in block copolymers dissolved in different solvents they had different viscosities and molecular conformations. The PSF-PEs block sopolymers had better solvent resistance than homo-polysulfone.
