It has been discovered that sequential polyperoxides can be beneficially used as initiators for vinylaromatic/diene copolymers to give high grafting values and reasonable molecular weights. A new cyclic diperoxide did not give these same results. The sequential polyperoxide initiators can be used as the only initiators or together with other conventional peroxide initiators to advantage. The polymerization rate can also be increased using these sequential polyperoxide initiators.
