Method for preparing supported catalyst for olefin polymerization, supported catalyst for olefin polymerization and method for preparing polyolefin using the same |
| abstract |
The present invention comprises the steps of (1) supporting an alkyl aluminum on a carrier; (2) A polar group selected from a hydroxy group (-OH), an amine group (-NH 2 ), a thiol group (-SH), a carboxyl group (-COOH), and an amide group (-CONH 2 ) on the carrier that has passed through the step (1) Supporting the aromatic compound having two or more bonds and one or more halogen groups bonded thereto; (3) supporting a cocatalyst containing an aluminoxane compound on the carrier passed through the step (2); And (4) supporting a main catalyst including a metallocene-based compound on the carrier passed through the step (3); a method for preparing a supported catalyst for olefin polymerization comprising, a supported catalyst for olefin polymerization prepared according to the method And it relates to a method for producing a polyolefin using the same. |
