AbstractSeveral types of cured black‐loaded rubbers, including natural rubber, butadiene/styrene copolymers, polybutadienes, and butyl rubbers, can be microtomed with an ultraviolet‐transparent solvent (methyl cyclohexane) as cutting liquid. The ultrathin sections obtained are used to characterize the rubber and the inorganic fillers, if any, and at the same time the antioxidant present is extracted rapidly from the very thin films by the solvent. An ultraviolet spectrum of the resultant extract enables some antioxidants and reaction products of cures to be rapidly characteri
