Abstract
A rubber composition contains: an elastomer matrix comprising at least one diene elastomer comprising epoxide functions, at least one reinforcing filler, and a system for crosslinking the polymer, comprising at least one organopolyphosphorus compound of general formula (I) in which A represents a covalent bond or a hydrocarbon group comprising at least 1 carbon atom, which is optionally substituted and which optionally comprises one or more heteroatoms, and the Rs represent, independently of one another, a hydrocarbon group comprising at least 1 carbon atom or a hydrogen atom.
