    摘要: A catalyst which comprises a compound of a transition metal in Groups 8 to 10 of the Periodic Table having a nitrogenous tridentate ligand, a clay, clay minteral, or lamellar ion-exchanging compound, an organosilane compound, and organoaluminum compound, etc.; and a process for producing a polyolefin with the catalyst. The catalyst is highly active, does not adhere to reactor walls, and can give a polyolefin excellent in powder morphology. Consequently, a polyolefin (especially polyethylene) can be industrially advantageously produced.

    摘要: Provided are an ethylene homopolymer having well-balanced properties of good heat resistance, good heat-sealability and good moldability, and its molded articles. The ethylene homopolymer is characterized in that the number of butyl branches per 100 methyl branches therein falls between 1 and 20, as measured through 13C-NMR, that its density, d (kg/m3), falls between 880 and 980, and that the density, d, and its melting point, Tm (° C.) , satisfy the conditions defined by the following formulae (1) to (3): Tm≧1.2×d−982 (980≧d≧925)  (1), Tm≧0.6×d−430 (925>d≧915)  (2), Tm≧0.16×d−28.4 (915>d≧880)  (3). The ethylene homopolymer is molded into moldings.
