| titleOfInvention | Catalyst composition and process for the production of olefinic polymers |
| abstract | A catalyst composition essentially comprises a compound (A) of the formula Me1R1p(OR2)qX14-p-q ..... I wherein R1 and R each are a C1 - C24 hydrocarbon group, X1 is a hydrogen or halogen atom, Me1 is titanium, zirconium or hafnium, p and q are 0 p 4, 0 q 4 and 0 p+q 4; a compound (B) of the formula MeR3m(OR4)nXz-m-n .... II wherein R3 and R4 each are a C1 - C24 hydrocarbon group, X is a hydrogen or halogen atom, Me is an element of Groups I - III in the Periodic Table, z is a valence of Me, and m and n are 0 m z, 0 n z and 0 m+n z; a cyclic compound (C) having two or more conjugated double-bonds; and a compound (D) of the formula R5R6C = CR7R8 ..... III and/or R9C CR10 ..... IV wherein R5 through R10 each are hydrogen or a C1 -C24 hydrocarbon group. The catalyst composition further incorporates a modified organoaluminum compound (E) having Al-O-Al bonds derived from the reaction of an organoaluminum compound with water, said organoaluminum compound being of the formula R17cAlX73-c wherein R17 is a hydrocarbon group such as an alkyl, alkenyl, aryl and aralkyl group of 1 to 18 carbon atoms, X7 is a halogen or hydrogen atom, and c is an integer of 1 c 3; and still further incorporates an inorganic and/or particulate polymer carrier (F), said inorganic carrier being formed from a porous inorganic compound of the group consisting of a carbonaceous material, metal, metal oxide, metal chloride, metal carbonate and mixtures thereof, and having a maximum length of 5 - 200 µm, a surface area of 50 - 1,000 m2/g and a pore volume of 0.05 - 3 cm3/g, and said particulate polymer carrier being formed from a thermoplastic or thermosetting resin having an average particle size of 5 - 2,000 µm. The disclosed catalysts find extensive use in the manufacture of olefinic polymers having a relatively wide molecular weight distribution as well as olefinic copolymers having a relatively narrow composition distribution, with a minimal use of aluminoxane. |
