Abstract
PURPOSE: To effect higher polymer yield per wt. of titanium and increased bulk density of the resalting polymer by polymerizing ethylene in the presence of a catalyst prepared from specific titanium-contg. solid catalytic componenet and organoaluminum compound.
CONSTITUTION: Ethylene is polymerized in the presence of a catalyst prepared from (A) a solid catalytic component and (B) an organoaluminum compound of formula AlR3 4 (R4 is 2W6C alkyl). The component (A) can be prepared as follows: a reaction product from (i) a halogenated aluminum of formula AlX3 1 (X1 is Cl, etc.) and (ii) an organosilicon comound of formula I(R1 and R2 are 1W8C alkyl, etc., n is 0W3) is made to react with (iii) a Grignard reagent of formula II (R3 is 1W8C alkyl; X2 is halogen) to obtain a solid, which is then catalysed by (iv) a titanium tetrahalide to obtain a titanium-contg. solid. The resulting solid is treated by (v) an orgainc acid ester and/or ether followed by catalysed by a titanium tetrahalide.
