摘要： The present invention relates to a hybrid supported metallocene catalyst and a polyolefin preparation method using the same. Using the hybrid supported metallocene catalyst can not only significantly reduce the amount of wax produced when polymerizing olefin monomers, but can also enhance the stress cracking resistance of the polyolefin that is prepared.

摘要： The present invention relates to polyolefin powder for preparing fiber, and fiber comprising the same. According to the present invention, provided is polyolefin, which exhibits a high molecular weight range and narrow molecular weight distribution and in which the formation of a gel deteriorating the quality of fiber is reduced. Therefore, by using the polyolefin, the present invention exhibits molecular weight, density and narrow molecular weight distribution, which are equivalent to those of conventional polyolefin, but the number of gels having a large particle diameter is remarkably reduced, and therefore, the present invention can provide fiber having excellent tenacity and tensile strength half-life.
