| titleOfInvention | PROCESS FOR PRODUCING .alpha.-OLEFIN POLYMERS |
| abstract | ABSTRACT OF THE DISCLOSURE A process for producing highly crystalline .alpha.-olefin polymers of good powder form with high yield is provided, which comprises polymerizing .alpha.-olefin in the presence of a preactivated catalyst obtained by reacting a reaction product (I) of organoaluminum compound (A1) with electron donor (B1), with TiC?4 to obtain a solid product (II); further reacting this solid product (II) with an electron donor (B2) and electron acceptor to obtain a solid product (III); during or/and after the reaction step for obtaining (II) or/and during or/and after the reaction step for obtaining (III), subjecting (II) or (III) to polymerization treatment with .alpha.-olefin; and combining the resulting final solid product with organoaluminum compound (A2) or (A2) and a reaction product (G) of organoaluminum compound (A3) with electron donor (B3) to obtain a preactivated catalyst; and preferably, in this combination, further subjecting a pact or the total of the catalyst to polymerization treatment with .alpha.-olefin in the presence of the final solid product and (A2) to obtain another preactivated catalyst. The catalyst has a superior storage stability and heat stability. |
