Document Type and Number:
Japanese Patent JP6600722
Kind Code:
B2
Abstract:
The present invention relates to a process for preparing a catalyst support comprising a layered double hydroxide (LDH), the process comprising, a) providing a water-wet layered double hydroxide of formula: [Mz+1-xM′y+x(OH)2]a+(Xn−)a/r.bH2O (1) wherein M and M′ are metal cations, z=1 or 2; y=3 or 4, x is 0.1 to 1, preferably x<1, more preferably x=0.1-0.9, b is 0 to 10, X is an anion, r is 1 to 3, n is the charge on the anion and a is determined by x, y and z, preferably a=z(1−x)+xy−2 b) maintaining the layered double hydroxide water-wet, c) contacting the water-wet layered double hydroxide with at least one solvent, the solvent being miscible with water and preferably having a solvent polarity (P′) in the range 3.8 to 9; and d) thermally treating the material to produce a catalyst support, a process for producing a solid catalyst, a polymerization catalyst as well as the use of an olefin polymerization catalyst in a polymerization process.
