(57) [Summary]nThe present invention relates to a catalyst composition comprising a metallocene, a co-catalyst, a support material and optionally further an organometallic compound. Although this catalyst composition is effectively used for polymerization of olefins, the catalyst composition of the present invention does not require the use of an aluminoxane such as methylaluminoxane (MAO) which is usually used in an excess amount as a co-catalyst, In addition, the catalyst activity is high, and a good polymer morphology is obtained. |
