Abstract
Process for the manufacture of an elastomer composition having a self-sealing property which is based on at least (phr meaning parts by weight per 100 parts of solid elastomer): a solid unsaturated diene elastomer; between 30 and 90 phr of a hydrocarbon resin; from 0 to less than 30 phr of filler; between 0.5 and 15 phr of thiuram polysulphide, in which, during a first stage or stage (a), a masterbatch comprising at least the solid unsaturated diene elastomer and between 30 and 90 phr of a hydrocarbon resin is prepared by mixing these various components in a mixer at a 'hot compounding' temperature or up to a 'hot compounding' temperature which is greater than the softening temperature of the hydrocarbon resin.
