Summary: | A process for manufacturing a self-sealing elastomer composition, said process comprising the following steps: a masterbatch, comprising at least one diene elastomer and more than 30 phr of a hydrocarbon resin, is firstly manufactured by compounding these various components in a mixer at a temperature or up to a temperature called the "hot compounding" temperature which is above the softening point of the hydrocarbon resin; and then at least one crosslinking system is incorporated into the masterbatch thus prepared, by compounding everything in the same mixer or in a different mixer, at a temperature or up to a temperature which is kept below 100° C., in order to obtain said self-sealing composition. |
