titleOfInvention | Olefin polymerization catalyst and process for producing ethylene copolymers |
abstract | An olefin polymerization catalyst comprising: n (A) a solid catalyst component containing a trivalent titanium, which is represented by the composition formula n n Mg.sub.m Ti(OR).sub.n X.sub.p [ED].sub.q n n (wherein R is a hydrocarbon group having 1 to 20 carbon atoms, X is a halogen, ED is a electron donative compound, and m, n, p and q are each a number satisfying 1≦m≦51, 0<n≦5, 5≦p≦106 and 0.2≦q≦2) obtained by reducing a titanium compound represented by the general formula Ti(OR 1 ) a X 4-a (wherein R 1 is a hydrocarbon group having 1 to 20 carbon atoms, X is a halogen atom and a is a number satisfying 0<a≦4) with an organomagnesium compound in the presence of an organic silicon compound having Si--O bonds and an organic porous polymer, treating the resulting solid product with a ester compound and then reacting it with titanium tetrachloride or a mixture of titanium tetrachloride and a electron donative compound, and n (B) an organoaluminum compound n and a process for producing an ethylene copolymer using the same. |
