Abstract: The present invention relates to equipment for preparing a polyolefin elastomer including a reactor to which a solvent and a raw material are supplied, a primary devolatilizer which devolatilizes a product discharged from the reactor to remove an unreacted material (primary devolatilization recovery flow), and to discharge the remainder thereof (primary devolatilization preparation flow), a secondary devolatilizer which re-devolatilizes the primary devolatilization preparation flow discharged from the primary devolatilizer to further remove an unreacted material (secondary devolatilization recovery flow), and to discharge the remainder thereof (secondary devolatilization preparation flow), a finisher which scrubs, using water, the secondary devolatilization preparation flow discharged from the secondary devolatilizer, so that the unreacted material and the water are evaporated and a polymer product remains, and a flash drum which removes low-molecular materials (impurity removal flow) from the primary devolat

Abstract: Provided are a novel transition metal complex where a monocyclopentadienyl ligand to which an amido or alcoxy group is introduced is coordinated, a method of synthesizing the same, and olefin polymerization using the transition metal complex. Compared to a conventional transition metal complex having a silicon bridge and an oxido ligand, the transition metal complex has a phenylene bridge, so that a monomer easily approaches the transition metal complex in terms of structure and a pentagon ring structure of the transition metal complex is stably maintained. The catalyst composition including the transition metal complex is used to synthesize a polyolefin copolymer having a very low density less than 0.910 g/cc.

Abstract: Provided are a supported metallocene catalyst which has excellent supporting efficiency due to an interaction between a cocatalyst supported on a carrier and a metallocene compound substituted with a functional group that can function as a Lewis base, such as acetal, ketal, tert-alkoxy alkyl, benzyloxy alkyl, substituted benzyloxy alkyl, monothioacetal, or monothioketal, and a method of polymerizing an olefin using the supported metallocene catalyst. In the supported metallocene catalyst, the metallocene catalyst is strongly bound to the carrier due to a Lewis acid-base interaction between the metallocene compound and the cocatalyst, and thus the metallocene catalyst is not separated from the carrier during the polymerization of polyolefin in a slurry or gas phase method. Thus, fouling is prevented and the prepared polymer has a good particle shape and a high apparent density. Thus, the supported metallocene catalyst can be suitably used in a conventional slurry or gas phase polymerization process.

Abstract: Provided are a bridged metallocene compound particularly suitable for copolymerization of ethylene and alpha-olefin or cyclic olefin, a process of preparing the metallocene compound, and a process of preparing polyolefin using the metallocene compound. The bridged metallocene compound has low steric hindrance and good (co)polymerization activity, and thus, exhibits good activity in copolymerization of ethylene and alpha-olefin such as 1-hexene or 1-octene. Furthermore, the process of preparing the bridged metallocene compound is simplified, and thus, suitable for mass production.
