摘要： A method for producing .alpha.-olefin polymers is provided. This method provides products having superior properties such as higher bulk density and uniform particle form which is close to sphere, with such an extremely higher catalyst efficiency that ash-removal step can be omitted without fear of coloring. The characteristic point of this method is in the improvement of conventional catalyst obtained by reacting a trivalent metal halide with a divalent metal hydroxide, oxide or carbonate or a double salt containing foregoing compounds or a hydrate of a compound containing a divalent metal to form a solid product (I), reacting an electron donor with said product (I), reacting the resulting product with a compound of transition metal of the 4th a or the 5th a group to form a final solid product and combining an organoaluminum compound with said final product,the improvement consisting in that said final product is obtained by reacting said solid product (I), said electron donor and said compound of transition metal, in the coexistence of said electron donor and said compound of transition metal.

摘要： Polymers of .alpha.-olefin such as polyethylene, polypropylene, copolymers of ethylene with propylene, butene-1 or styrene, are produced by the (co-) polymerization using a catalyst obtained by mill-mixing an oxide of a metal belonging to I, II, III, VII or VIII Group of the Periodic Table of Elements such as MgO or SiO.sub.2 or B.sub.2 O.sub.3, with a trivalent metal halide such as AlCl.sub.3, then reacting the resultant mixture with a transition metal compound such as TiCl.sub.4 in the presence of an aromatic compound such as xylene, and activating the resultant solid reaction product with an organoaluminum compound such as triethyl aluminum.In the preparation of the present catalyst, no dehydrochlorination occurs. The present catalyst has an excellent utilization efficiency of transition metal compound in the polymerization. Further, no polymer film forms on the wall surface of the polymerization vessel.

摘要： In a method for producing a polymer or a copolymer of ethylene carried out in the presence of a catalyst obtained by a combination of a solid product containing a transition metal of the fourth a or fifth a group and an organoaluminum compound, an improvement has been made to provide a catalyst having such an efficiency as being capable of omitting ash-removal step and providing a high production yield of polymer per unit volume of polymerization vessel per hour and a polymer having a high B.D. Said catalyst can be obtained by (1) reacting a halide of trivalent metal (A) with a divalent metal compound or its derivative (B) such as hydroxide, oxide or carbonate thereof, or hydrate of these, to produce a solid product (I); (2) reacting said solid product (I) with a chain or cyclic polysiloxane having a general formula of ##EQU1## WHEREIN R.sub.1 and R.sub.2 are same or different kinds, and each mean hydrogen atom, alkyl, aryl, halogen atom, alkoxy, aryloxy radical or a residual radical of an aliphatic carboxylic acid and n is a number in the range of 3-10,000 to produce a solid product (II), and (3) further reacting said solid product (II) with a liquid transition metal compound (D) to produce a solid product (III).

摘要： Ethylene can be polymerized or copolymerized by the use of a catalyst prepared by mixing a trivalent metal halide with a metal carbonate or/and a metal hydrogen carbonate, reacting the resulting mixture with a transition metal compound in the presence of an aromatic compound, and activating the resulting solid product with an organoaluminum compound.By substituting said metal carbonate or/and metal hydrogen carbonate for metal salt hydrates, sulfide hydrates, hydroxides or hydroxide hydrates, or metal oxides in our prior art, drawbacks such as dehydrochlorination in the preparation of catalyst or difficulty in removal of catalyst residue from polymer can be overcome while various advantages in our prior art are still maintained.
