摘要：

Bulk functionalization of EPDM rubber with maleic anhydride (MAH) using peroxide type initiators led to high grafting efficiency after optimization of reaction conditions. Reaction behavior in the presence of two aromatic peroxides was studied. It was verified that for a fixed initiator concentration the main process control variables were shear rate, mixing temperature, and MAH content in the charge recipe. The formulations containing high MAH levels exhibited anomalous low grafting efficiencies, which could be mechanistically explained by the presence of MAH excited species.
