METHOD FOR PREPARING SUPPORTED METALLOCENE CATALYST, AND SUPPORTED METALLOCENE CATALYST USING THE SAME

摘要

PURPOSE: A manufacturing method of a supported metallocene catalyst is provided to improve the selectivity to a copolymer and catalytic activity of a supported metallocene catalyst without the leaching phenomenon of a catalyst and a co-catalyst. CONSTITUTION: A manufacturing method of a supported metallocene catalyst comprises a step of supporting a first co-catalyst which is an organic aluminum compound; a step of supporting a hetero metallocene catalyst in the support; a step of supporting a borate compound-containing second co-catalyst into the support. The support amount of the first co-catalyst is 3-10 mmol/1 based on 1g of the support and the support amount of the second co-catalyst is 0.01-0.5 mmol based on 1g of the support.
