摘要：
An olefin polymerization catalyst comprising:
(A) a solid catalyst component containing a trivalent titanium, which is represented by the composition formula
Mg m Ti(OR) n X p [ED] q
(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 a X 4-a (wherein R¹ is a hydrocarbon group having 1 to 20 carbon atoms, X is a halogen atom and a is a number satisfying 0
(B) an organoaluminum compound,
and a process for producing an ethylene copolymer using the same.
