摘要： The present invention relates to an olefin polymer and a preparation method thereof. The olefin polymer exhibits excellent mechanical strength and high processability, and thus is expected to be utilized as a material for various products. Particularly, the olefin polymer can be stably produced into films by a melt-blowing process and thus is expected to be usefully used as a material for products prepared by a melt-blowing process.

摘要： The present invention relates to a polyolefin which exhibits a narrow molecular weight distribution, high strength, and a high stretching ratio, and a preparation method therefor. According to the present invention, it is possible to provide polyethylene with high catalyst activity, high molecular weight, and controlled molecular weight distribution by using, in polymerization of an olefin monomer, a hybrid supported metallocene catalyst in which a borate compound is used as a second cocatalyst. In addition, if the polyolefin is processed, it is possible to produce a fiber with excellent mechanical properties and an excellent stretching ratio.

摘要： The present invention relates to ethylene-1-hexene-1-butene terpolymer and a film including the same. The ethylene-1-hexene-1-butene terpolymer according to the present invention has an optimized range of density and melt index and includes 1-hexene and 1-butene as comonomers, and can provide a polymer showing excellent properties by regulating the content ratio of the comonomers in a certain range. Therefore, the film prepared by using the same can be usefully used because it has excellent stickiness, processibility, and falling dart impact strength which are especially suitable for stretch films.
