ABSTRACT:
An aminosilane of the formula: ##STR1## where R.sub.1 is a linear or branched C.sub.1-22 alkyl or C.sub.3-22 cycloalkyl, which may be substituted with at least one halogen atom; R.sub.2 is a bis(linear or branched C.sub.1-22 alkyl or C.sub.3-22 cycloalkyl)amino, a substituted piperidinyl, a substituted pyrrolidinyl, decahydroquinolinyl, 1,2,3,4-tetrahydroquinolinyl or 1,2,3,4-tetrahydroisoquinolinyl, with the substituent selected from the group consisting of C.sub.1-8 alkyl, pheny. C.sub.1-8 linear or branched alkylsubstituted phenyl and trimethylsilyl, with the proviso that when the substituent is C.sub.1-8 alkyl, there must be at least two such substituent groups present and R.sub.1 must contain halogen; and R.sub.3 is a linear or branched C.sub.1-8 alkyl or C.sub.3-8 cycloalkyl. The aminosilane may be reacted with an aluminum-alkyl compound and a solid component comprising a titanium compound having at least one titanium-halogen bond and an electron donor, both supported on an activated anhydrous magnesium dihalide, to form a catalyst for polymerization of olefins.
