Effect of Quinone Derivatives and Sulfhydryl Compounds on Swelling of Poly(4-Vinylpyridine) Gels in Organic-Solvents
Interactions of sulfhydryl compounds and quinone derivatives with poly(4-vinylpyridine) gels have been studied. Adsorption of long-chain sulfhydryl compounds onto gels causes the gel to swell, whereas oxidation of the adsorbed sulfhydryl compound to disulfide by a quinone derivative results in the gel shrinking. The higher the donating ability of the sulfhydryl compound, the stronger its interaction with a quinone derivative and thus the faster the removal from the gels, as revealed by HPLC.
