Description

  The present invention relates to modified particles capable of producing a high molecular weight addition polymer, a catalyst component for addition polymerization, a catalyst for addition polymerization, and a method for producing the addition polymer.

Olefin polymers such as polypropylene and polyethylene are widely used in various molding fields because they are excellent in mechanical properties, chemical resistance, etc. and have a good balance between their properties and economy.
In recent years, these olefin polymers are produced by a so-called single-site catalyst in which a transition metal component composed of an isolatable transition metal compound (for example, a metallocene complex or a nonmetallocene compound) and an organometallic component composed of an aluminoxane or the like are combined. A production method in which an olefin or the like is addition-polymerized by using a polymer has been proposed.
Since ordinary single-site catalysts are soluble in a polymerization solvent, when applied to a polymerization in which an addition polymer forms particles such as slurry polymerization or gas phase polymerization, uniform shaped addition polymer particles are formed. It is difficult to obtain, and coarse or fine particles are generated, bulk polymers are generated, or these adhere to the polymerization reactor wall, resulting in poor heat removal of the polymerization reactor, resulting in decreased productivity. For example, Patent Document 1 describes that a specific particle is used as one of the catalyst components as a solution to the problem that the stable operation is difficult.

JP 2003-171413 A

In the production of an addition polymer, the molecular weight of the resulting addition polymer is adjusted with hydrogen gas. That is, if a large amount of hydrogen is introduced into the polymerization system, the molecular weight is generally lowered. From the viewpoint of design, it is preferable if a high molecular weight addition polymer can be obtained even in the presence of high concentration hydrogen, since the range of molecular weight design is widened.
Under such circumstances, the problem to be solved by the present invention, that is, the object of the present invention is to provide modified particles capable of producing a high molecular weight addition polymer, a catalyst component for addition polymerization, a catalyst for addition polymerization, and an addition polymer. It is in providing the manufacturing method of.
