对苯二酚型蛇笼氧化还原树脂结构的设想与论证

The Supposing and Proving of Hydroquinone Snake-Cage Redox Resin Structure

根据模板聚合理论与对苯二酚型蛇笼氧化还原树脂的性能实验结果,设想本树脂具有蛇笼氧化还原结构,被吸留于其中的对苯二酚-甲醛线形树脂是能起氧化还原作用的“蛇”,交联基体树脂是“笼”。通过电镜实验及该树脂中的对苯二酚-甲醛线形树脂的抽提实验和红外光谱与氮元素定量分析实验,论证了我们所设想的结构模式。

In this paper, the snake-cage redox structure pattern of the resin is supposed in accordance with the theory of template polymerization and the experimental results on the redox properties of the resin, 717 cross-linking matrix resin(a Chinese commercial product) is considered to be'a cage', the linear hydroquinone-formaldehyde (in equal moles) polymer occluded within the matrix resin should be considered as 'a snake',which has a redox function. The resin above is simply called HSR.The main experimental evidences of this structural pattern; (1) The snake-cage structure photographs of HSR have been shown by electron microscope; (2) It has been proved by analysing the IR spectra of the extraction solution for HSR-tetrahydrofuran that hydroquinone-formaldehyde polymer in HSR is linear; (3) It was shown by using the spectra of HSR standing in the oxidation or reduction state that there is an oxidation or reduction group in HSR,and the mutual change between the two kinds of groups can be carried out; (4) The experimental quantitative value of N element of HSR is consistent with that calculated according to our structural pattern.
