摘要
A new procedure has been developed successfully to prepare the maleimide-terminated poly (arylene ether sulphone ) oligomers. It was condueted by the aromatic nucleophilic substitution of the chloro-terminated poly (arylene ether sulphone) oligomer by an endblocking monomer, N-(4-hydroxyphenyl) maleimide. The reaction and structure of the product were confirmed by FT-IR. 1H-NMR and elemental analysis.
