Synthesis and Characterization of PSA-PEG Block Copolymer Based on Polysulfonamide and Amine-Terminated Polyethylene Glycol

摘要：

A novel PSA-PEG block copolymer was synthesized by polycondensation of aromatic polysulfonamide and amine-terminated polyethylene glycol. The structure of the copolymer was characterized by IR spectra. The solubility test proved that the solubility of copolymer was changed in l-methyl-2-pyrrolidinone (NMP),N,N-dimethylformamide (DMF) and N,N- dimethylacetamide (DMAc) with the addition of PEG. And the most suitable spinning solution concentration of copolymer/DMAc was 14％~16％. TGAtest indicates that copolymers still maintain excellent thermal stability.
