Abstract: A process for the production of EPDM comprising reacting ethylene, propylene, ethylidene norbornene, and hydrogen, in the gas phase, in a fluidized bed, under polymerization conditions, in the presence of a catalyst system comprising:
(a) the reaction product of a vanadium compound and a electron donor; (b) at least one modifier having the formula BX₃ or AlR (3-a) X a wherein each R is alkyl or aryl and alike or different; each X is independently chlorine, bromine, or iodine; and a is 0, 1, or 2, wherein components (a) and (b) are impregnated into an inorganic support;
(c) a halocarbon promoter; and (d) a hydrocarbyl aluminum cocatalyst with the following proviso:
(i) the partial pressure of ethylene is in the range of about 25 to about 200 psi; (ii) the molar ratio of propylene to ethylene is in the range of about 0.2:1 to about 2:1; (iii) the molar ratio of hydrogen to ethylene is in the range of about 0.0001:1 to about 0.01:1; and (iv) the amount of ethylidene norbornene is about 1.5 to about 15 percent by weight based on the weight of the fluidized bed.
