Chinese patent 200910180602.9 discloses a kind of preparation method of load type non-metallocene catalyst, and it is that magnesium compound and Nonmetallocene title complex are dissolved in the solvent, obtains load type non-metallocene catalyst after the drying.Patent 200910180605.2 discloses a kind of preparation method of load type non-metallocene catalyst; It is that magnesium compound and Nonmetallocene title complex are dissolved in the solvent; Add precipitation agent, make it deposition, obtain load type non-metallocene catalyst after the filtration washing drying such as hexane.What these two kinds of methods adopted is the magnesium compound carrier, the particle form of catalyzer is difficult to control, has limited the polymer beads form that polymerization thus obtains.

Patent 200910180603.3,200910180604.8,200910210989.8,200910210986.4,200910210985.X, 200910210990.0 disclosed load type non-metallocene catalyst preparing methods and above-mentioned patent are similar; What all use is that magnesium compound is as carrier; Still exist the particle form of catalyzer to be difficult to control, limited the polymer beads form that polymerization thus obtains.

Patent CN200710162666.7 discloses loaded catalyst, load type non-metallocene catalyst and preparation method thereof, and it is to have in the presence of the alcohol, magnesium compound is dissolved in the tetrahydrofuran solvent; Add porous support, behind the convection drying with titanium tetrachloride reaction, load non-metallocene metal complexes more at last; Catalyst activity is higher; And the polymkeric substance that obtains of polymerization has high bulk density thus, owing to form comparatively complicatedly, needs chemical processing agent to handle complex carrier; And because the existence of alcohol can exert an influence to the performance of Nonmetallocene title complex intrinsic performance.

Even so; The ubiquitous problem of the load type non-metallocene catalyst that exists in the prior art is; The load process is complicated, load non-metallocene metal complexes again after the multistep that generally need carry out carrier is handled, and olefin polymerizating activity is low and be difficult to regulate; And, when carrying out olefinic polymerization, must assist higher promotor consumption in order to improve its polymerization activity.For the carrier loaded non-metallocene catalyst of porous support list, carrier needs after thermal activation treatment to handle with the chemical reagent of its reaction with aluminum alkyls etc. again, and needs strict control preparation condition for the carrier loaded non-metallocene catalyst of magnesium compound list.
