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.
一种氨基硅烷的化学式:##STR1## 其中R.sub.1是线性或支链的C.sub.1-22烷基或C.sub.3-22环烷基,可以被至少一个卤素原子取代; R.sub.2是双(线性或支链的C.sub.1-22烷基或C.sub.3-22环烷基)氨基,取代的哌啶基,取代的吡咯烷基,十氢萘基,1,2,3,4-四氢萘基或1,2,3,4-四氢异喹啉基,取代基被选择为由C.sub.1-8烷基,苯基,C.sub.1-8线性或支链烷基取代的苯基和三甲基硅基组成的群,前提是当取代基是C.sub.1-8烷基时,必须至少有两个这样的取代基存在,并且R.sub.1必须含有卤素; R.sub.3是线性或支链的C.sub.1-8烷基或C.sub.3-8环烷基。该氨基硅烷可以与铝烷化合物和固体组分反应,该固体组分包括至少具有一种钛-卤素键和一个电子给体的钛化合物,两者都支持在活性无水二卤化镁上,以形成用于聚烯烃聚合的催化剂。
