There are provided (I) a process for producing a copolymer of ethylene, an alpha-olefin having from 3 to 20 carbon atoms and optionally a polyene, through feeding the components (A), (B), (C2) and (D) to a polymerization reactor, comprising the steps of causing ethylene, alpha-olefin having from 3 to 20 carbon atoms and optionally the polyene for copolymerization: (A) a transition metal complex, (B) an organic aluminum compound, (C2) a halogen-containing compound, which is a derivative of an aryl group-containing carboxylic acid, and (C3) a halogen-containing compound, which is not a derivative of a carboxylic acid, and (D) a Lewis base. |
