摘要：
Solid catalyst components for the polymerization of olefins, comprising titanium, magnesium and a compound of general formula (I), wherein R1 and R2 may be the same or different and each represents a linear or branched hydrocarbon group having 1 to 20 carbon atoms, and n is an integer of 1 to 10, as an electron donor, which are combined with organoaluminum compounds to form polymerization catalysts for the production of olefin polymers. This electron donor has no problems of safety and hygiene, and is inexpensive and easily synthesized. This compound can provide highly active and highly stereoregular solid catalyst components for the polymerization of olefins, catalysts for the polymerization of olefins, and processes for producing olefin polymers.
