    摘要: Provided are a solid catalyst component for olefin polymerization and a catalyst comprising the component for olefin polymerization, in which the electron donor is free from the problem of lacking in safety and sanitation, and is inexpensive and easy to produce, and which exhibit high activity in producing olefin polymers with high stereospecificity, and also a method for producing olefin polymers in the presence of the catalyst. The solid catalyst component comprises titanium, magnesium and an electron donor compound of formula (I): wherein R1 and R2 each represent a linear or branched hydrocarbon residue having from 1 to 20 carbon atoms; R3 represents an alicyclic hydrocarbon residue having from 3 to 20 carbon atoms; and n represents an integer of from 1 to 10. The solid catalyst component is combined with an organic aluminium compound to prepare a catalyst, which is used in producing olefin polymers.
