    • Disclosed are a catalyst for polymerizing olefins containing a solid catalyst component containing titanium, magnesium and halogen as essential components (component (A)); an organic aluminum compound (component (B)); and a silane compound (component (C)) represented by general formula (1) wherein R1 and R2 independently represent a straight, branched or cyclic saturated aliphatic hydrocarbon group or a silyl group, a method of preparing polyolefins using the catalyst as well as novel trimethoxysilane compounds represented by the general formula (1) in which R1 is a straight saturated aliphatic hydrocarbon group having 2 to 10 carbon atoms, and R2 represents a methyl group. Use of the catalyst enables efficient production of polyolefins having a low molecular weight (MFR>20 (g/10 minutes)), a broad molecular weight distribution (MLMFR/MFR>22) and a high stereoregularity when applied to polymerization of olefins having 3 or more carbon atoms.
