摘要:
Disclosed is a process for producing a procatalyst composition having an amide ester internal electron donor. The process includes pre-halogenating a procatalyst precursor before reaction with the amide ester and forming the procatalyst composition. Ziegler-Natta catalyst compositions containing the present procatalyst composition exhibit improved catalyst activity and/or improved catalyst selectivity and produce propylene-based olefins with broad molecular weight distribution.

摘要:
The present disclosure provides processes for the production of substituted phenylene aromatic diesters and the resultant compositions. The processes include reacting an aromatic diol with an aromatic carboxylic acid or a derivative thereof. The aromatic diol and/or the aromatic carboxylic acid (or derivative thereof) is/are substituted. The reaction forms a substituted phenylene aromatic diester with the structure (II): wherein R1-R14 are the same or different. At least one of R1-R14 is selected from a substituted hydrocarbyl group having 1 to 20 carbon atoms, an unsubstituted hydrocarbyl group having 1 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, a heteroatom, and combinations thereof.
摘要:
Disclosed are procatalyst compositions having an internal electron donor which includes a substituted amide ester and optionally an electron donor component. Ziegler-Natta catalyst compositions containing the present procatalyst compositions exhibit improved catalyst activity and/or improved catalyst selectivity and produce propylene-based olefins with broad molecular weight distribution.
摘要:
Disclosed are halogenated amide esters that are suitable as internal electron donors in procatalyst compositions. Ziegler-Natta catalyst compositions containing the present procatalyst compositions exhibit improved catalyst activity and/or improved catalyst selectivity and produce propylene-based olefins with broad molecular weight distribution.

摘要:
Disclosed are catalyst compositions having an internal electron donor which includes a 3,6-di-substituted-1,2-phenylene aromatic diester. Ziegler-Natta catalyst compositions containing the present catalyst compositions exhibit very high hydrogen response, high activity, high selectivity and produce propylene-based olefins with high melt flow rate.
