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 said 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.

A rubber composition containing at least:
- an elastomer matrix comprising at least one diene elastomer comprising epoxide functions;
- a reinforcing filler;
- and
- a system for crosslinking the at least one diene elastomer, the system 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
- each R represents, independently of one another, a hydrocarbon group comprising at least 1 carbon atom or a hydrogen atom.
An organopolyphosphorus compound of general formula (II)
- in which:
- each R1 represents, independently of one another, a hydrocarbon group comprising at least 1 carbon atom or a hydrogen atom, and
- A1 represents a divalent hydrocarbon group mainly composed of units of type (IIa),
- —(O—R′)n— (IIa),
- in which:
- R′ represents a divalent hydrocarbon group comprising at least 1 carbon atom, and
- n represents an integer greater than or equal to 2.
