  • TIRE COMPRISING A RUBBER COMPOSITION COMPRISING AN EPOXIDE POLYMER CROSSLINKED WITH A POLYCARBOXYLIC ACID
    Publication number: 20150322234
    Abstract: A tire comprises a rubber composition based on at least one polymer comprising epoxide functional groups, at least one reinforcing filler and a system for crosslinking the polymer. The system for crosslinking the polymer comprises a polycarboxylic acid of general formula (I): in which A represents a covalent bond or a hydrocarbon group which comprises at least 1 carbon atom, which is optionally substituted and which is optionally interrupted by one or more heteroatoms, and an imidazole of general formula (II): in which R1 represents a hydrocarbon group or a hydrogen atom, R2 represents a hydrocarbon group, and R3 and R4 represent, independently of one another, a hydrogen atom or a hydrocarbon group, or else R3 and R4 form, together with the carbon atoms of the imidazole ring to which they are attached, a ring.
