Abstract: 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 HSRhave been shown by electron microscope; (2) It has been proved by analysing the IRspectra of the extraction solution for HSR-tetrahydrofuran that hydroquinone-formaldehyde polymer in HSRis linear; (3) It was shown by using the spectra of HSRstanding 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 Nelement of HSRis consistent with that calculated according to our structural pattern.

Key words: Hydroquinone, Snake-cage structure, Redox resin
