Abstract:
A process for crosslinking a polymer having units derived from at least one conjugated diene monomer, units derived from at least one unsaturated nitrile monomer and units derived from at least one derived unsaturated acid monomer, comprising the step of crosslinking the polymer in the presence of one or more coupling/condensing agent(s), wherein the polymer is hydrogenated and wherein the coupling/condensing agent is SOCl2, PCl5, PBr3, oxalyl chloride, phosgene, trifluoroacetic anhydride, organometallic agents, diazomethane, alcohols, and carbodiimides or their derivatives having the general formula RN&boxH;C&boxH;NR.
