METALLOCENE CATALYST SYSTEM COMPRISING OPERATIONALLY STABLE COMPOSITION, AND METHOD FOR PRODUCING POLYOLEFIN BY MEANS OF METALLOCENE CATALYST SYSTEM

WIPO Patent Application WO/2018/101794

A9

The present invention relates to a metallocene catalyst system comprising an operationally stable composition, and a method for producing polyolefin by means of the metallocene catalyst system. More specifically, by utilizing the metallocene catalyst system comprising: 90-99.9 wt% metallocene compound of one or more types; and 0.1-10 wt% operationally stable composition comprising one or more types of compounds selected from the group consisting of sulfate, sulfonate, phosphate, and carboxylate, and one or more types of white mineral oil, the unique activity of the catalyst is maintained and fouling and agglomeration phenomena are minimized during olefin polymerization to allow the process to be stably carried out, and thus by means of the present invention, a method for producing polyolefin can be provided, and produced polyolefin can be provided.
