Abstract
The present invention relates to a tire puncture sealant and a pneumatic tire containing such puncture sealant as a built-in puncture sealant. The sealant composition contains silica reinforcement and butyl rubber depolymerized in the presence of a balanced and cooperative combination of organoperoxides comprised of a minor amount of 4,4-di(tertiary butylperoxy) valerate depolymerization initiator and a major amount of dicumyl peroxide depolymerization propagator, the combination of which has been observed to have a synergistic effect.
