Abstract
The invention relates to a coupling agent to provide the coupling of a metal element to a vulcanizable elastomeric material whereby the coupling agent provides both binding to the metal element and reaction with the vulcanizable elastomeric material. The coupling agent comprises a macromolecular backbone and at least one functional endgroup. The functional endgroup is responsible for the binding to the metal element. The backbone has a molecular weight ranging between 1000 and 10000 and has at least one unsaturated carbon-carbon bond for reacting with the vulcanizable elastomeric material. The invention further relates to an article comprising a metal element at least partially embedded in a vulcanizable elastomeric material and comprising a coupling agent to provide the coupling of the metal element to the vulcanizable elastomeric material.
