METHOD FOR MANUFACTURING HYBRID SUPPORTED METALLOCENE CATALYST, AND METHOD FOR MANUFACTURING POLYPROPYLENE USING HYBRID SUPPORTED METALLOCENE CATALYST

摘要

The present invention relates to a method for manufacturing a hybrid supported metallocene catalyst, and a method for manufacturing polypropylene using the hybrid supported metallocene catalyst. The method for manufacturing a hybrid supported metallocene catalyst according to the present invention is possible to control a composition ratio of a meso isomer and a racemic mixture of a metallocene compound by a simple method through heat treating a catalyst composition in the presence of an aromatic hydrocarbon solvent to increase a content of the meso isomer. Therefore, it is possible to provide polypropylene which has excellent catalytic activity and in which a content of a xylene-soluble fraction is controlled to meet desired mechanical properties.;COPYRIGHT KIPO 2019
