Process for the manufacture of a self-sealing elastomer composition comprising at least one diene elastomer, one hydrocarbon resin with a given softening temperature and one liquid plasticizing agent, characterized in that it comprises the following successive stages: (a) incorporating the hydrocarbon resin in the diene elastomer by kneading these components in a mixer at a temperature or up to a temperature referred to as “hot compounding” temperature greater than the softening temperature of the hydrocarbon resin, in order to obtain a masterbatch; (b) incorporating the liquid plasticizing agent in the masterbatch by kneading the combined mixture in the same mixer or in a different mixer, in order to obtain the self-sealing composition; and (c) forming the said self-sealing composition dimensionally.
