The present invention provides a continuous process for producing an adducted derivatized EPM or EPDM oil solution in which a grafted ethylene polymer is adducted with an antioxidant diamine for formation of an adduct during holding.

In a gas-phase fluidized-bed polyethylene reactor using a Ziegler catalyst under operating conditions, a co-catalyst, such as triethyl aluminum, is added to the reactor by mixing the TEA with some of the feed ethylene and pumping the solution into the reactor.
