Abstract
The supported Ziegler-Natta catalyst utilizing MgCl
2
as carrier holds paramount significance in the synthesis of polyolefins
notably polyethylene and polypropylene. The inherent characteristics of the carrier of Ziegler-Natta catalyst-activated MgCl
2
such as particle structure and morphology
play an important role in regulating the spatial distribution and electronic effects of active species
which then determine the catalytic features of the final Ziegler-Natta catalyst (such as catalytic activity and stereoselectivity). This article provides a comprehensive review on the influences of activation methods of MgCl
2
carrier on the morphology
structure
and composition of the carrier precursors and the prepared Ziegler-Natta pre-catalysts
and the olefin catalytic properties of the pre-catalysts. Based on the industrial applications of the various pre-catalysts
the high-performance polyolefin catalysts in the future are prospected.
