Catalyst components for polymerization of olefins and use thereof

摘要

Disclosed is a catalyst component for the polymerization of olefins, which is a compound having the following structure: wherein R<1> is a hydrocarbon radical having 1 to 10 carbon atoms or a halogen-containing hydrocarbon radical having 1 to 10 carbon atoms, and R<2>s are each a hydrogen atom, a halogen atom, a siloxy group, a lower-alkyl-substituted siloxy group or a hydrocarbon radical having 1 to 10 carbon atoms, or which is a reaction product of the following sub-components (i) and (ii): sub-component (i) which is a compound having the formula R<1>-B-(OH)2 in which R<1> is a hydrocarbon radical having 1 to 10 carbon atoms or a halogen-containing hydrocarbon radical having 1 to 10 carbon atoms; and sub-component (ii) which is an organoaluminum compound. ole
