Metallocene catalyst and preparing process of styrenic polymer using the same |
| abstract |
Disclosed herein is a metallocene catalyst for use in the preparation of a styrenicnpolymer or copolymer. This metallocene catalyst contains a siloxy group introduced into annancillary ligand bonded to a central metal of a transition metal compound. The introduction ofnthe siloxy group is achieved by a reaction of the transition metal compound with a hydroxynfunctional group-containing silicone compound. The use of the metallocene catalyst of thenpresent invention provides a styrenic polymer or copolymer having an excellent stereoregularity, anhigh melting point, and improved molecular weight and molecular weight distribution, even whennit is used in combination with a small amount of a cocatalyst. |
