Description
Technical field
The present invention relates to catalyst field is and in particular to a kind of catalyst component for olefin and catalyst.
Background technology
It is known that Ziegler-Natta（Z-N）Catalyst, can be used for CH2=CHR olefinic polyreaction, particularly exists
Have in 3 carbon or the alpha-olefine polymerizing of more carbon atom and can obtain higher yields and the polymer of higher stereospecificity.
As Ziegler-Natta（Z-N）The catalytic component of the important component of catalyst（Or ingredient of solid catalyst）, be with magnesium,
Titanium and internal electron donor are as basis.But, various internal electron donors are necessarily special in the corresponding polyolefin products of imparting
Also product can be made to have some shortcomings, thus limiting their application while point.Research worker wishes to find combination property
More excellent Z-N catalyst.
Specifically, the now widely used active height of Z-N catalyst containing phthalic acid ester internal electron donor, tree
The feature of fat good combination property, but phthalic acid ester is proved injure the fertility of the mankind, thus recently do not contain adjacent benzene
The Z-N catalyst of dicarboxylic acid esters internal electron donor becomes study hotspot.
Molecular weight distribution（MWD）The mechanical performance of impact polymer and processing characteristics.High molecular weight moieties are to a great extent
The upper long term mechanical strength determining polymer, and low molecular weight fraction determines its extrusion performance to a great extent.
The disclosed active height of Z-N catalyst containing 1,3- diol ester internal electron donor of CN1213080C, molecular weight distribution
Wide feature, but the molecular weight distribution of its preparation is wide not enough, thus limiting its application.EP990201172 and
The active height of Z-N catalyst of succinate-containing internal electron donor disclosed in US60999436, stereotaxises ability is good, gained
The wide feature of molecular weight distribution, but this catalyst is to molecular weight regulator（Hydrogen is the molecular-weight adjusting being most frequently with
Agent）Sensitivity is bad, that is, in identical hydrogen usage, the melt flow rate (MFR) (MFR) of polymer（Or title melt index）Low；
And be to meet injecting products, the especially processing request of thin wall parts, polymer generally requires higher MFR.Producing injection
With when homopolymer or anti-impact polymer it is often desirable to polymer has high MFR to have wide molecular weight distribution simultaneously.This polymerization
Thing is considered intensity and the rigidity that existing good processing characteristics has also had.
Supported catalyst component with alkoxyl magnesium as carrier, obtained acrylic polymers, there is particle shape excellent
Good, ultra-fine powder content is few（Micropowder amount conference impact polymer continuously produces）, the premium properties such as stereoregularity height.However,
With alkoxyl magnesium as carrier, the catalyst for olefines polymerizing solid constituent of function admirable to be obtained is it may first have to prepare performance
Excellent alkoxyl magnesium carrier.The present inventor discloses one kind in Chinese patent CN102453150A and urges for alkene
Compound alcohol alkoxyl magnesium carrier of agent preparation and preparation method thereof；By this alkoxyl magnesium carrier, titanium compound and O-phthalic
When the catalyst solid constituent of esters of gallic acid internal electron donor reaction preparation and corresponding olefin polymerization catalysis are used for olefinic polymerization
Activity is high, can obtain the olefin polymer that particle shape is excellent, ultra-fine powder content is few, stereoregularity is high.However, this catalysis
The vistanex molecular weight distribution of agent preparation is wide not enough.
Content of the invention
For deficiency of the prior art, the invention provides a kind of catalyst component for olefin（Or title catalyst
Solid, ingredient of solid catalyst）And the catalyst containing described catalytic component, the electron donor body in described catalytic component
System（Internal electron donor a and internal electron donor b）There is synergism.Described catalyst is used for olefinic polymerization, has polymerization activity
Height, stereotaxises ability is good, and hydrogen response is good, molecular weight distribution width, and does not contain phthalic acid ester in polymer；
Especially under high hydrogen concentration, the catalysis activity of catalyst and the polymer isotacticity of Geng Gao can be improved by a larger margin.
