MANUFACTURING METHOD OF A HYBRID SUPPORTED METALLOCENE CATALYST CAPABLE OF MANUFACTURING POLYOLEFIN WITH HIGH BULK DENSITY EVEN WITH HIGH ACTIVITY OF OLEFIN POLYMERIZATION

摘要

PURPOSE: A manufacturing method of a hybrid supported metallocene catalyst is provided to provide a hybrid supported metallocene catalyst having high catalytic activity of olefin polymerization by low cost and simplified process.;CONSTITUTION: A manufacturing method of a hybrid supported metallocene catalyst comprises: a step of treating carrier with the water content of 4-7 weight% by trialkylaluminum at the temperature of 60-100°C; a step of dipping alkylaluminoxane into the carrier; and a step of dipping a metallocene compound into the carrier. The carrier comprises hydroxy group of 2-4 mmol/g on surface thereof. The molar ratio of the trialkylaluminum and the alkylaluminoxane is 1:10-1:30.;COPYRIGHT KIPO 2012
