Abstract
Abstract The sorption of amines, hydroxy amines, and naphthols from water and ethyl alcohol by synthetic rubbers was studied with the help of an interferometer and a SF-4 spectrophotometer. It was shown that: 1. SBR (SKS-30) sorbs a large amount of 1-naphthylamine, less of the 1- and 2-naphthols and m-toluidine and m-hydroxydiphenylamine to an insignificant degree. 2. The degree of sorption of 1- and 2-naphthols from water is inversely proportional to their dipole moments and correlates with their activity as antioxidants. 3. The polar rubber (SKN-40) absorbs from ethyl alcohol the amines the best, the hydroxy amines poorly, and an insignificant amount of 2-naphthol. 4. The amines in a decreasing magnitude of sorption on SKN-40 from alcohol fall in a series (phenyl-2-naphtholamine > 2-naphthylamine > diphenylamine) which correlates with their activity as antioxidants. 5. The electronegative OH group, sticking out of the body of the molecule, exerts an influence on the degree of sorption of m-hydroxyphenyl...
