    Abstract: The new metallocene catalysts according to the present invention are prepared by reacting a metallocene compound with a compound having at least two functional groups. The metallocene compound is a transition metal compound which a transition metal is coordinated with a main ligand such as cycloalkanedienyl group and an ancillary ligand. The functional groups of the compound having at least two functional groups are selected from the group consisting of a hydroxy group, a thiol group, a primary amine group, a secondary amine group, etc. The metallocene catalysts according to the present invention have a structure which an ancillary ligand of a metallocene compound is bonded with functional groups. A structure of the metallocene catalysts can be varied according to the metallocene compounds, the compound having at least two functional groups, and the molar ratio of each reactant. The metallocene catalyst is employed with a co-catalyst for styrene and olefin polymerization. The co-catalyst is an organometallic compound and a mixture of non-coordinated Lewis acid and alkylaluminium. The organometallic compound is usually alkylaluminoxane and organoaluminium compound. The syndiotactic polystyrenes and the polyolefins having good physical properties are prepared by using the metallocene catalyst according to the present invention. A monomer for polymerization includes styrene, derivatives of styrene, and a compound having ethylenically unsaturated double bonds Those compounds are homopolymerized and copolymerized to give polystyrene and polyolefin.

    Abstract: In producing a catalyst used for synthesis of an unsaturated aldehyde and an unsaturated carboxylic acid by a gas-phase catalytic oxidation, there is used a step of packing an additive-containing catalyst precursor of the catalyst into a tubular reactor, passing a gas through the tubular reactor, and elevating, in this state, the temperature of the additive-containing catalyst precursor so that a temperature of the gas at an outlet of the catalyst precursor layer becomes higher than a temperature of the gas at an inlet of the catalyst precursor layer. The step makes possible easy and highly reproducible production of a high-performance catalyst which is small in the reduction in catalytic performance caused by, for example, the thermal decomposition of the additive contained in the catalyst precursor.

    Abstract: Catalyst systems useful for olefin polymerization are disclosed. The catalysts include a bimetallic complex that incorporates two linked indenoindolyl groups, each of which is pi-bonded through its cyclopentadienyl ring to one of the metals Compared with conventional indenoindolyl complexes, the bimetallic complexes of the invention have enhanced ability to give polyolefins with desirably low melt indices. Certain bimetallic indenoindolyl complexes also provide a way to broaden polymer molecular weight distribution and thereby improve processability simply by regulating the amounts of comonomer and activator used in the polymerization.
