| 摘 要： | 报道了一种全新的1,4-bis(-2,2,6,6-tetramethyl-4-piperidyl-1-oxyl)butadiin(BIPO)及其聚合物——聚BIPO的合成方法,并对BIPO和聚BIPO的磁性进行了详细的研究。证明了认为聚BIPO的铁磁性是由无机物质引起的观点是不正确的。

| Abstract: | In this paper the new method of synthesis of 1, 4-bis- (2,2,6, 6-tetramethyl-4-oxy-piperidyl-1-oxyl)butadiin(BIPO)and its polymer (PolyBIPO)was reported. The procerdure of reaction was much simpified. The magnetic properties of BIPO and PolyBIPO was studied in detail. Ferromagnetism due to transition metals impurities can be ruled out by contrasting the magnetism of the monomer and its polymer. |
