Title:
新規な化合物、これを含む触媒組成物およびこれを用いた環状オレフィン系重合体の製造方法
Document Type and Number:
Japanese Patent JP5769711
Kind Code:
B2
Abstract:
The present invention relates to a novel metallocene compound, a catalyst composition including the compound and an olefin polymer prepared using the same. The metallocene compound and the catalyst composition can be used for preparing the olefin polymer with high copolymerization degree and high molecular weight. Particularly, the block copolymer with high heat resistance can be prepared by using the metallocene compound, and the olefin polymer with high melting point (Tm) can be obtained, even if co-monomer is used at an increased amount in preparation of olefin polymer.
