The vulcanization of butyl rubber by p ‐quinone dioxime oxidized by red lead and tetrachloroquinone was investigated. The maximum physical effective crosslinking density of the vulcanizates appeared to be when p ‐quinone dioxime and the oxidizing agent were equimolar. The formation of one physical effective crosslink required one molecule of p ‐quinone dioxime. Chemical reactions are suggested for the vulcanization steps.
