| titleOfInvention |
Conjugated diene compound polymerization catalyst, process for the preparation of conjugated diene polymer in the presence thereof and polybutadiene thus prepared |
| abstract |
The present invention provides a process for the production of a conjugated diene polymer having a controlled microstructure at a high polymerization activity in the presence of a metallocene type complex of compound of transition metal of the group V of the Periodic Table. A novel catalyst is provided comprising (A) a metallocene type complex of a transition metal of the group V of the Periodic Table, (B) an ionic compound of a non-coordinating anion and a cation, (C) an organic metal compound of the groups I to III and (D) water, wherein the molar ratio of (C)/(D) is from 0.66 to 5. A novel process for the production of a conjugated dime polymer is also provided, which comprises the polymerization of a conjugated diene compound in the presence of a catalyst comprising (A) a metallocene type complex of a transition metal of the group V of the Periodic Table, (B) an ionic compound of a non-coordinating anion and a cation, (C) an organic metal compound of the groups I to III and (D) water, wherein the molar ratio of (C)/(D) is from 0.66 to 5. |
