Abstract

The invention relates to an elastomeric composition comprising a branched polymer obtained from a polymer selected from the group consisting of NBR, HNBR, XHNBR, EP(D)M, and maleized EPDM and from a compound adapted to form a bond at a bond of the polymer to form a side chain. This compound comprises a group Y comprising a perfluoroalkyl functional group and a functional group adapted to react with the double bond. Preferably, Y=F(CFCF)/wherein m is in the range between 2 and 20; R is selected from the group consisting of a double bond C═C, a triple bond C≡C, a functional alcoholic, carboxylic, esteric, acrylic, methacrylic group. The invention also relates to the use of a composition as a body compound for a drive belt and to the use thereof in an oil bath.
