The mechanism of chemical reaction of various oxime compounds in the peroxide cure of ethylenepropylene rubber was studied. From the results, it was found that : (1) p-Quinone dioxime did not accelerate the decomposition of dicuniyl peroxide, but it formed crosslinking by the reaction with the polymer radicals. The structure of the crosslinking by p-quinone dioxime was different from that by dicumul peroxide alone. (2) p, p′-Dibenzoyl quinone dioxime which is a derivative of p-quinone dioxime produced a large amount of benzoyl radicals and caused more crosslinking than p-quinone dioxime.
