Oligo(ether sulfones). 3. Block copolymers via condensation reactions of telechelic oligo(ether sulfones) bearing phenolic endgroups and oligomeric α,ω-diols

摘要

Block copolymers containing polyether components as soft and hydrophilic segments and functionalized poly(ether sulfone)s bearing ester and carboxylic groups as hard segments were synthesized. Nuclear magnetic resonance and Fourier transform infrared spectra, and differential scanning measurements were used to characterized the resulting polymer. The prepared block copolymer maybe useful in the medical area, such as material contact with living tissue or as materials for semipermeable membranes which may be modified chemically to optimize the permselectivity and mechanical stability.
