Patent ID: RE42957

Claim:
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 R 1 , R 2 , R 3 , R 4 , R 5 , R 8 , R 9 and R 12 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; R 6 and R 11 are identical and are each a hydrocarbon group or a silicon-containing group , or may be bonded together to form a ring structure ; R 7 and R 10 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 ; R 6 and R 7 may be combined to form a ring structure; R 10 and R 11 may be combined to form a ring structure; R 13 and R 14 are 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.
