Process for producing olefin polymers

A process for producing an olefin polymer, comprising:

• carrying out solution polymerization of ethylene and one or more kinds of monomers selected from α-olefins at a temperature ranging from 120 to 300° C., in the presence of a catalyst for olefin polymerization, said catalyst comprising:
• (A) a bridged metallocene compound represented by the general formula [I] described below,
• wherein R1, R2, R3, R4, R5, R8, R9 and R12 are each a hydrogen atom, a hydrocarbon group, or a silicon-containing group, and may be identical or different, or neighboring groups may be bonded together to form a ring structure;
• R6 and R11 are identical and are each a hydrocarbon group or a silicon-containing group, or may be bonded together to form a ring structure;
• R7 and R10 are identical to each other and are each a hydrocarbon group or a silicon-containing group, or may be bonded together to form a ring structure;
• R13 and R14 each an aryl group, and may be identical or different;
• M is Ti, Zr or Hf;
• Y represents carbon or silicon;
• Q represents halogen, a hydrocarbon group, an anionic ligand, or a lone electron pair, and may be selected from an identical or different combination of neutral ligands capable of coordination;
• and
• j is an integer of 1 to 4, and
• (B) at least one compound selected from the group consisting of
• (b-1) an organoaluminum oxy compound,
• (b-2) a compound which reacts with the bridged metallocene compound (A) to form an ion pair, and
• (b-3) an organoaluminum compound.
