| abstract | A process for the production of polyethylenes or EPRs comprising contacting a mixture comprising ethylene, one or more alpha-olefins, and, optionally, a diene, under polymerization conditions, with a catalyst system comprising: (A) a catalyst precursor comprising: (i) a vanadium compound, which is the reaction product of (a) VX3 wherein each X is independently chlorine, bromine, or iodine; and (b) an electron donor, which is a liquid, organic Lewis base in which VX3 is soluble; (ii) a modifier having the formula BX3 or AlR(3-a)Xa wherein each R is independently alkyl having 1 to 14 carbon atoms; each X is as defined above; ant a is 0, 1, or 2; and (iii) a support for said vanadium compound and modifier, said catalyst precursor being in an independent or prepolymerized state, (B) a cocatalyst consisting of a compound having the formula AlR(3-a)Xa wherein R and X are as defined above and a is 1 or 2; and (C) a promoter consisting of a saturated or an unsaturated aliphatic halocarbon having at least 3 carbon atoms and at least 6 halogen atoms, or a haloalkyl substituted aromatic hydrocarbon wherein the haloalkyl substituent has at least 3 halogen atoms. |
