| 摘 要： | Polyethylene oxide with sulfadiazine and hydroxyl end groups (PEOsf) were prepared by anion ring-opening polymerization of ethylene oxide initiated by sodium 4-amino-N-(2-pyrimidinyl)benzene sulfonamide (SF-Na). The product was characterized in detail by NMR, IR, GPC and DSC. Its molecular weight and molecular weight distribution are in the range of 1200-1 500 and 1.04-1.06 respectively, and the latter is nearly monodistribution. The trace of the moisture from air could accelerate the polymerization, and the mechanism is discussed.
