Abstract
A catalyst for polymerization of olefins formed from (A) a solid catalyst component containing magnesium, titanium, halogen, and an electron donor compound, (B) an organoaluminum compound shown by the formula, RAlQ, and (C) an aminosilane compound shown by the formula, RSi(NRR); and a process for producing a catalyst for polymerization of olefins in the presence of the catalyst are provided. A novel aminosilane compound, a catalyst component for polymerization of olefins having a high catalytic activity, capable of producing polymers with high stereoregularity in a high yield, and exhibiting an excellent hydrogen response, a catalyst, and a process for producing olefin polymers using the catalyst are provided.
