| 摘 要： | 研究了聚(2,2,6,6-四甲基-4-羟基哌啶-1-氧基)丁二炔的合成,并经元素分析、红外光谱及电子顺磁共振波谱确定了它的结构。利用提拉样品磁强计对其磁化特征的研究表明,SIPO有明显的顺磁性而相应的聚合物-PolySIPO有一定的铁磁性,利用单体与聚合物的磁性对比研究,证明了PolySIPO的铁磁性不是无机杂质引起的。

| Abstract: | The authors communicate their synthesis of poly(2,2,6,6 - tetramethyl - 4 -oxy -piperidyl - 1 - oxyl) butadiin (polySIPO ) and then their findings on the chemical composition and physical properties of polySIPO and its monomer as determined by IR,ESR,and ultimate analysis.The static magnetic susceptibility and the magnetization of polySIPO and SIPO were measured on an extracting sample magnetometer. It has been shown that SIPO shows paramagnetism but its polymer (polySIPO ) displays ferromagnetism. Ferromagnetism due to transition metal impurities can be ruled out by atomic absorption spectrometry and by contrasting the magnetism of polySIPO and SIPO. |
