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