Catalyst impregnated on fine silica, process for preparing, and use for ethylene polymerization |
| abstract |
Film grade ethylene copolymers are prepared by copolymerizing ethylene with at least one C3 to C8 alpha olefin employing a catalyst formed from an organo aluminum activator compound and a precursor composition impregnated in very fine particle sized porous silica, said precursor composition having the formula MGmTi1(OR)nXp[EDq] wherein R is a C1 to C14 aliphatic or aromatic hydrocarbon radical, or COR' wherein R' is a C1 to C14 aliphatic or aromatic hydrocarbon radical; X is selected from the group consisting of Cl, Br, I or mixtures thereof; ED is an electron donor compound; m is >/=0.5 to </=56; n is 0, 1 or 2; p is >/=2 to </=116; and q is >/=2 to </=85; and said organo aluminum activator compound having the formula Al(R'')cX'dHe wherein X' is Cl or OR'''; R'' and R''' are the same or different and are C1 to C14 saturated hydrocarbon radicals; d is 0 to 1.5; e is 1 or 0; and c+d+e=3. |
