Abstract

A family of supported Ziegler catalysts, suited for propene polymerization were studied for more than ten years, beginning in the early 70’s. The solid precatalyst used for all the studies can be described by a common formula: MgCl2-E.D.-TiCl4, in which the electron donor (E.D.) is almost always an aromatic ester (A.E.), generally ethylbenzoate (E.B.). The preparation chiefly differs in the way the three components are reacted together by milling or impregnation, the temperatures, the durations and the ratios used.1
