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.
