Description
Technical field
The present invention relates to be used to prepare the manufacture method of solid catalyst component for olefin polymerization, catalyst for olefines polymerizing and the olefin polymer of the homopolymer of alpha-olefin or multipolymer.
Background technology
Usually, olefin polymer uses Z-N (Ziegler-Natta) catalyzer that is made of titanium compound and organo-aluminium compound to carry out polymerization.For example, in the polyacrylic preparation of one of olefin polymer, use contains mainly by titanium, magnesium, the solid catalyst component that chlorine and electron donability compound constitute, organo-aluminium compound as the cocatalyst composition, with the catalyzer that has the silicoorganic compound of alkoxyl group as containing of taxis rising agent, obtain isotactic polyprophlene, at present, just be devoted to the research of following several respects: the catalyst activity when improving polymerization, improve the taxis of olefin polymer, improve polymer powder form that is used for the stably manufactured olefin polymer and the residual C1 that reduces polymkeric substance etc.
If the residual C1 in the polymkeric substance is many, for example, can cause the corrosion of mould in the injection molding, or moisture absorption and foaming when biaxially oriented film or spinning, or produce and to contain the foreign matter of additive, thereby make the high-speed molding difficulty, therefore the residual C1 that reduces in the polymkeric substance is great problem.
In addition, as the means that solve the problem of residual C1 in the polymkeric substance, usually, the firstth, the method that activity of such catalysts is improved, the secondth, carry out load magnesium compound on inorganicss such as silicon-dioxide, make magnesium chloride composition in the catalyzer, be that C1 forms the method that reduces in fact.
For example, the known silicon-dioxide that makes, butyl octyl magnesium, hydrogen chloride gas contacts and the silica supports of generation magnesium chloride load, it is handled the method (spy opens clear 63-280707 communique) of back loading titanium tetrachloride and electron donor compound with alcohol, make silicon-dioxide, butyl octyl magnesium contact and the product that obtains contacts with the mixture of silicon tetrachloride and trichlorosilane, thereby obtain the silica supports of magnesium chloride load then with the inert solvent washing, it is handled the method (the flat 4-506833 communique of special table) of back loading titanium tetrachloride and electron donor compound with alcohol.
In addition, knownly make silicon-dioxide, butyl ethyl magnesium, ethanol contact and the silica supports of magnesium ethylate that generated load, carry out heptane wash after making the reaction of itself and silicon tetrachloride, make titanium tetrachloride and its under the electron donor compound, 90 ℃ each only reacts 1 time method (spy opens clear 61-174206 communique) making under 50 ℃ then; Thereby the mixture that makes magnesium chloride, butanols contains and is dipped in the silicon-dioxide silica supports of butanols ligand of magnesium chloride that generated load, makes the method (spy opens clear 63-168413 communique) of its load titanium tetrachloride and electron donor compound; Make diethoxy magnesium-supported to the silicon-dioxide of handling with trimethylsilyl chloride in advance, make the method (special fair 7-17695 communique) of its load titanium tetrachloride and electron donor compound.
But, though the olefin polymer that obtains with these methods has certain performance, particularly can not be fully satisfied at aspects such as polymerization activity, taxis, residual C1.
On the other hand, be purpose with forms such as the particle diameter that improves olefin polymer and shapes, the spy open disclose in clear 58-000811 communique etc. once be dissolved into magnesium compound in the pure equal solvent after, use once more the method for precipitate.
But, since these methods need carry out magnesium compound load, dissolve and processing such as separate out, therefore very complicated on operation, and have the shortcoming that lacks catalyst performance stabilised.Catalyst activity when in addition, these methods also have polymerization and the unfavorable shortcoming of the taxis of olefin polymer.
Therefore, improvement method as these shortcomings, open in flat 02-413883 communique etc. the spy and to disclose the use MAGNESIUM METAL, the resultant of reaction of alcohol and specified quantitative halogen is as the method for support of the catalyst, in addition, a kind of manufacture method of using the olefin polymer of Ziegler-Natta catalyst is disclosed in the fair 07-025822 communique of spy, described Ziegler-Natta catalyst contains solid catalyst component, this solid catalyst component is that organic acid acetic is joined alkoxyl magnesium, in the resultant of reaction of halogenating agent and titan-alkoxide, halogenated titanium and its reaction are made.
In addition, known a kind of method (spy opens clear 64-69608 communique) of using solid catalyst component to prepare olefin polymer, this solid catalyst component is to make diethoxy magnesium outstanding turbid in alkylbenzene, under the temperature more than 80 ℃, below 120 ℃, make quantitative titanium tetrachloride, Bisphthalate and its reaction, with alkylbenzene the solid matter that obtains is washed, in the presence of alkylbenzene, make quantitative titanium tetrachloride and the reaction of this solid matter obtain.
But, these methods when polymerization catalyst activity and the taxis of olefin polymer on still undesirable.
In addition, open in the flat 11-269218 communique the spy and to disclose a kind of solid catalyst component for olefin polymerization, this solid catalyst component is in the presence of the electron donability compound, after making magnesium compound under the temperature more than 120 ℃, below 150 ℃ and titanium compound contacting, under the temperature more than 100 ℃, below 150 ℃, obtain with inert solvent washing, the effect of acquisition be when making polymerization catalyst activity through the time reduce controlled and the taxis of olefin polymer be improved.
