Abstract: The present disclosure discloses an arylaminosilane compound, a propylene polymerization catalyst and preparation thereof. The arylaminosilane compound has a structure of wherein R1 is a C1-C8 alkyl group or a C1-C8 silanyl group; R2, R3, R4, R5 and R6 are each independently H or a C1-C12 alkyl group; R7, R8 and R9 are each independently a C1-C8 alkyl group or a C1-C8 alkoxy group. When the arylaminosilane compound is used as an external electron donor of a propylene polymerization catalyst in propylene polymerization reaction, the catalyst has good hydrogen response.

Abstract: The present invention relates to a catalyst for propylene polymerization, a catalyst system for propylene polymerization and preparation and use thereof. The catalyst for propylene polymerization comprises: an activated magnesium halide, a titanium compound supported on the activated magnesium halide containing at least one Ti-halogen bond, and an internal electron donor compound selected from one or more of compounds having a structure of below Formula (1), wherein R1 and R6 are each independently selected from a C1-C12 straight or branched alkyl, a C3-C15 cycloalkyl or aryl, and R′ is H, a C1-C5 straight or branched alkyl, or phenyl; R2, R3, R4, and R5 are each independently selected from H, halogen, a C1-C12 straight or branched alkyl, a C3-C8 cycloalkyl, a C6-C15 aryl, or arylalkyl. The present invention can provide a catalyst showing high polymerization reaction activity and excellent stereospecificity, by applying a novel type of internal electron donor.
