SUPPORTED NON-METALLOCENE CATALYST, PREPARATION METHOD AND APPLICATION THEREOF

摘要

A simple and easy method for preparing supported non-metallocene catalyst is disclosed, which includes the following steps: dissolving magnesium compound and non-metallocene ligand in solvent, mixing optional porous carrier and the obtained magnesium compound solution, drying the obtained mixture or adding precipitator into the obtained mixture, treating the obtained supported carrier with chemical treating agent selected from ?B group metal compounds to obtain supported non-metallocene catalyst. Polymerization activity of the said catalyst is flexible and adjustable. The said supported non-metallocene catalyst can be used in olefin homopolymerization /olefin copolymerization with less cocatalyst.
