Title:
HYDROGENATION OF METALLOCENE
Document Type and Number:
Japanese Patent JPH10139792
Kind Code:
A
Abstract:

To provide a method for hydrogenating a metallocene by which a hydrogenated metallocene used for production, etc., of stereoregular polyolefin is obtained in a high yield by treating the metallocene having a double bond, an aromatic substituting group, etc., with hydrogen in a non halogenated solvent and in the presence of a hydrogenation catalyst.

A metallocene having at least one double bond and/or at least one aromatic substituting group, and at least one kind of transition metal compound of group IVb in the periodic table of elements is treated hydrogen in at least one kind of non halogenated solvents comprising a non halogenated aromatic solvent such as benzene, toluene and xylene and/or a non halogenated non protonic solvent containing oxygen such as anisole, ethyl phenyl ether and tetrahydrofuran, in the presence of at least one kind of hydrogenation catalyst such as palladium-activated carbon, palladium black, platinum oxide and platinum black at 0-150°C to provide a hydrogenated metallocene used for production of a polyolefin such as isotactic polypropylene, a copolymer and an elastomer.
