气相法全密度聚乙烯高效催化剂的研究

The Research of High - efficiency Catalyst for Gas - phase method All Density Polyethylene

主要讲述了一种结构式为[(MgBuCl)_p,(MgCl(?))](?)[Ti(OBu)xCl_y]_b(THF)_c[(C_eH_(?)_2AlCl]_d的齐格勒-纳塔型催化剂的制备方法.该催化剂具有活性高、共聚能力强、氢调敏感的特性,并且在气相聚合反应过程中放热均匀、操作稳定,适合在我国引进的大型气相流化床工艺装置上使用.

This paper discusses mainly the preparation method of a kind of Ziegler - Natta catalyst with a structure of may be [(MgBuCI) P(MgCb]a[Ti(OBu)xCly ]b(THF)c[(CeH5) 2AlCl]d. The catalyst possesses some good performances such as high catalytic efficiency ; good for copolymerigation reaction; and sensitive with hydrogen. When this catalyst is used in gas - phase polymerization technology, it sents out heat uniformly and operates steadily. The catalyst is suitable for use in imported large scale gas - phase fluidize bed reactor,the author suggested.
