| titleOfInvention | Process for the production of polyethylene |
| abstract | A process for the polymerization of ethylene or a mixture comprising ethylene and one or more alpha-olefins and, optionally, a diene, comprising passing, under polymerization conditions, the aforementioned monomer(s) into contact with a catalyst system comprising:n (a) the reaction product ofn (i) a titanium based catalyst precursor having the formula Mg a Ti(OR) b X c (ED) d wherein n ED is an electron donor n R is an aliphatic or aromatic hydrocarbon radical having 1 to 14 carbon atoms or COR' wherein R' is an aliphatic or aromatic hydrocarbon radical having 1 to 14 carbon atoms; n each OR group is the same or different; n each X is independently chlorine, bromine, or iodine; n a is 0.5 to 56; n b is 0, 1, or 2; n c is 2 to 116; and n d is 2 to 85; and (ii) at least one activator having the formula n n n n Al(R') e X' f H g n n n nwherein n X' is Cl or OR'' n R' and R'' are the same or different and are saturated hydrocarbon radicals having 1 to 14 carbon atoms n f = 0 to 1.5 n g = 0 or 1 n n e+f+g = 3 ; and n n (iii) an alkyl, alkoxy, aryl, or aryloxy phosphine oxide, or mixtures thereof, in an amount sufficient to replace about 1 to about 80 mole percent of the electron donor in the precursor, and in a molar ratio of phosphine oxide to titanium of 0.1:1 to 8:1 n wherein component (a) is impregnated into an inorganic support; and (b) a hydrocarbyl aluminum cocatalyst. |
