    摘要： Terpolymers of propylene (as a main monomer), ethylene and another a-olefin having superior and well-balanced physical properties, are produced substantially without forming soluble polymer by preliminarily activating a catalyst consisting of a titanium trichloride component and a specified organoaluminium halide, with a small amount of an a-olefin of 2 to 12 carbon atoms, a trialkylaluminium and an aromatic ester, and copolymerizing specified amounts of propylene, ethylene and an α-olefin of 4 to 12 carbon atoms in the presence of the preliminarily activated catalyst.

    摘要： A catalytic ingredient for use in the polymerization of olefins comprises a carrier comprising a magnesium compound precipitated from solution and a catalytic component supported on the carrier and which is a titanium halide, vanadyl halide or vanadium halide, the catalyst being obtained by a process which comprises the steps of:

    (A) mixing (a) one or more magnesium compounds of the formulae Mg(OR¹) n (OR²) 2-n and/or MgR 3 m (OR) 2-m (in which R¹, R², R³ and R⁴ are the same or are different and each is a C₁-C₂₀ alkyl group, an allyl group, a C₃-C₂₀ cycloalkyl group or a C₅-C₂₀ aromatic group; and m and n are the same or are different and each has a value of from 0 to 2), with (c) a saturated or unsaturated monohydric alcohol of the general formula, R⁵OH (in which R⁵ is a C₁-C₂₀ alkyl group, allyl group, a C₃-C₂₀ cycloalkyl group, or a C₅-C₂₀ aromatic group), or a polyhydric alcohol having from 1 to 20 carbon atoms, for reaction in solution in the presence of (b) carbon dioxide in an inert hydrocarbon solvent, to obtain component (A);
    (B) subjecting component (A) to mixing and reaction with (d) a titanium halide of the formula TiX p (OR⁶) 4-p and/or a vanadyl halide of the formula VOX q (OR⁷) 3-q and/or a vanadium halide of the formula VX r (OR⁸) 4-r and/or a silane halide of the formula SiX s (OR⁹) 4-s (in which X is Cℓ or Br; each of R⁶, R⁷, R⁸ and R⁹ is a C₁-C₂₀ alkyl group, an allyl group or C₃-C₂₀ cycloalkyl group; each of p, r and s is an integer of from 1 to 4; and q is an integer of from 1 to 3); together with (e) a siloxane compound having an -Si-O-Si- bond alone or in admixture with a silane compound of the formula SiR 10 t  (OR¹¹) 3-t (in which R¹⁰ and R¹¹ are each a C₁-C₂₀ alkyl group, or allyl group, a C₃-C₂₀ cycloalkyl group or a C₅-C₂₀ aromatic group; and t has a value of from 0 to 3), thereby giving solid product (I);
    (C) reacting solid product (I) with (f) a saturated or unsaturated monohydric alcohol of the formula R¹²OH (in which R¹² is a C₁-C₂₀ alkyl group, allyl group, a C₃-C₂₀ cycloalkyl group or C₅-C₂₀ aromatic group) or a polyhydric alcohol having up to 20 carbon atoms and (g) a cyclic ether thereby causing dissolution and re-precipitation to give solid product (II); and
    (D) subjecting solid product (II) to further reaction with (g) component (B) consisting of a titanium halide and/or a vanadyl halide and/or a vanadium halide as defined for (d) above, thereby to give solid product (III): followed by further reaction with a mixture of component (B) and (h) an electron donor thereby obtaining solid product (IV) for use as the catalytic component.
