Abstract
A process for preparing titanized chromium catalysts on a carrier, comprises following steps: A) bringing a support material into contact with a protic medium comprising a titanium compound and a chromium compound, B) optionally removing a solvent, C) optionally calcining a precatalyst obtained after step B), and D) optionally activating the precatalyst obtained after step B) or C) in an oxygen-containing atmosphere at from 400 DEG C to 1100 DEG C.
Description
The present invention relates to the chrome catalysts of the titanizing on the carrier of the novel copolymerization that is used for ethylene homo reaction and ethene and alpha-olefin, the purposes that is used to prepare their method and is used for olefinic polyreaction.
For example, can use the titanium compound on the carrier, Ziegler-Natta catalyst as is well known, perhaps use the chromium cpd on the carrier, philip catalyst as is well known prepares the multipolymer of Alathon and ethene and higher alpha-olefin such as 1-butylene, 1-amylene, 1-hexene or 1-octene by polyreaction.For example, when the homopolymer that uses ethene and multipolymer were used for blown-film extrusion, polymkeric substance has good harmony between mechanical property and processing characteristics be very important.
Known, the chrome catalysts on the carrier is suitable for producing the ethylene copolymer with good mechanical property very much.The polymer properties that obtains in polyreaction depends on the preparation method of the chrome catalysts of use, especially the type that depends on solid support material, as the type of the chromium cpd of its chemical structure, composition, surface-area or pore volume, use, polyvoltine compound more, as application order or the roasting and the activation method of the existence of titanium compound, aluminum alkyls or carbon monoxide, various components.The parent material that it is to use combines with the step that is applied to carrier, and the chrome catalysts that it has generated expection subsequently is used to prepare the polymkeric substance that has for the desired performance characteristic of application-specific.
Chrome catalysts on the carrier is titanizing normally, and promptly they not only comprise chromium cpd but also comprise the titanium compound of variable ratio, for example can influence molar mass distribution and HLMI (high load melt index) by means of these titanium compounds.Titanium compound is normally finished in the preparation process at hydrogel in the application on the carrier, has generated SiO
2-TiO
