A method for the degradation of nitrile rubber (NBR) by metathesis in presence of a catalyst (I), involves performing the reaction in presence of a phosphane or diphosphane (II) in amounts of 0.01-1 eq (II) per 1 eq (I). An independent claim is included for a method for the production of hydrogenated NBR by hydrogenation of the product obtained by the degradation of NBR as in the above method. |
