A hydroxyl-functional polymer is reacted with a compound ZCO.N(H)x.N(H)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 to the rubber backbone.
羟基官能团聚合物与化合物 ZCO.N(H)x.N(H)x.CO.OR 反应,其中 Z 为卤素或芳基氧基,x 为 0 或 1,R 为烃,必要时将反应产物氧化,得到偶氮二甲酸官能团聚合物,其式为 QOCO-N:N-CO-OR,其中 Q 为惰性聚合物基团。 这种聚合物用于与乙烯不饱和天然橡胶或合成橡胶反应,以便将聚合物衍生的基团接枝到橡胶主干上。
