    Abstract: 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.

    Abstract: The present invention relates to a method for olefin oligomerization and comprising i) injecting an olefin monomer and a solvent into a continuous stirred tank reactor (CSTR); ii) injecting an oligomerization catalyst system comprising a ligand compound, a transition metal compound, and a co-catalyst into the continuous stirred tank reactor; and iii) performing a multimerization reaction of the olefin monomer, wherein a ratio of the flowing rates of the olefin monomer and the solvent is from 1:1 to 2:1. In the method for olefin oligomerization according to the present invention, high linear alpha-olefin selectivity may be attained even with a small amount of a solvent used by controlling reaction conditions during the multimerization reaction of olefin by a continuous reaction using a continuous stirred tank reactor.

    Abstract: The present invention relates to a method for preparing a hybrid supported metallocene catalyst. More specifically, the present invention relates to a method for preparing a hybrid supported metallocene catalyst by using two or more different types of metallocene compounds. One type of the metallocene compounds shows a high polymerization activity even when it is supported, and thus the catalyst has an excellent activity and can be utilized in the polymerization of olefinic polymers having ultra-high molecular weight. Based on the hybrid supported metallocene catalyst obtained according to the preparation method of the present invention, an olefinic polymer having high molecular weight and the desired physical property can be prepared.
