Abstract
The present invention provides olefin polymerization catalysts which can produce olefin polymers with excellent polymerization activity and an olefin polymerization method using the catalyst, wherein the catalyst comprises a transition metal amide compound represented by general formula (I) below: ##STR1## where M.sup.1 is Ti, etc.; R.sup.1 is alkyl, (substituted) phenyl, etc.; R.sup.2 is C(R.sup.5).sub.2 C(R.sup.6).sub.m C(R.sup.5).sub.2 -- or --C(R.sup.5).sub.2 --X.sup.1 --C(R.sup.5).sub.2 -- (X.sup.1 representing a silicon-containing group, etc., and R.sup.5 and R.sup.6 representing hydrocarbon groups, etc.); and R.sup.3 is a hydrocarbon group or halogen, etc.; and at least one compound selected from among organoaluminum oxy-compounds, ionizing ionic compounds and organometallic compounds.
