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.

Rubber compositions comprising an epoxide diene elastomer and a cross-linking system

A modified polymer is obtained by grafting at least one compound of formula (I) to at least one unsaturation of the chain of an initial polymer in which Q represents a dipole comprising at least one nitrogen atom; A represents an arenediyl ring, optionally substituted by one or more hydrocarbon-based chains, which are identical or different, independent of one another, and are optionally substituted or interrupted by one or more heteroatoms; E represents a divalent hydrocarbon-based bonding group which may optionally contain one or more heteroatoms; R, Rand Rrepresent, independently of one another, a hydrogen atom or a hydrocarbon-based chain which is optionally substituted or interrupted by one or more heteroatoms; and n is an integer having a value greater than or equal to 1.

Grafted polymer bearing pendent cyclic carbonate functional groups

A rubber composition based on a reinforcing filler and on an elastomer comprising units of a 1,3-diene monomer and bearing carbonate functions, each present in a 1,3-dioxolan-2-one ring is provided. The composition has improved reinforcement.
