A hydroxyl-functional polymer is reacted with a compound ZCO.N(H).sub.x.N(H).sub.x.CO.OR, where Z is halogen or aryloxy, x is 0 or 1 and R is hydrocarbon, and the reaction product is if necessary oxidized to give an azodicarboxylate functional polymer having the formula QOCO.N:N.CO.OR where Q is an inert polymer group. This polymer is used to react with ethylenically unsaturated natural or synthetic rubber so as to graft groups derived from the polymer on the rubber backbone.
