Abstract
PURPOSE: To provide the title catalyst by which a polymer of high stereo-regularity is obtd. without requiring a waste catalyst removing process by using a solid substance obtd. by reacting a solid reaction product of an org. Mg cpd. sol. in hydrocarbon and a Si-H bond-contg. chlorosilane cpd. with Ti chloride and carboxylic acids or pulverizing them.
CONSTITUTION: A soln. of n org. Mg cpd. of formula ° sol. in hydrocarbon is reacted with a chlorosilane cpd. of formula II as a reaction reagent, forming a solid substance. In formula I, at least one of R' and R" is 4, 5 or 6C sec. or tert. alkyl or a 6 or more C hydrocarbon radical, 0≤u≤2, 0≤v≤2 and u+v=2. In formula II, a≥0, b≥0, a+b≤4 and R is a hydrocarbon radical. The solid substance, TiCl4 or TiCl3, and a carboxylic acid or its derivative are reaction pulverized or pulverized. The resulting solid catalyst component is combined with an org. Al cpd. optionally mixed with a carboxylic acid or its derivative, giving the title olefin polymn. catalyst of high activity.
