Abstract
The fluidized bed polymerization process of Specification 968,139 is modified by activating the catalyst by polymerizing a polymerizable hydrocarbon in a preliminary suspension of the catalyst. In the examples the catalyst is formed by reducing TiCl4 with Al(C2H5)3 to form the purple modification of TiCl3 to a suspension of which in n-pentane or propane are added Al (C2H5)2Cl and propylene. The so formed catalyst is then used for the fluidized bed polymerization of propylene. Specifications 954,798 and 968,139 are referred to.ALSO:A suspension of the purple modification of TiCl3, used as a polymerization catalyst component (see Division C3), is formed by reacting solutions of TiCl4 and Al(C2H5)3 in propane or n-pentane at 170 DEG C. under pressure. Specifications 954,798 and 968,139 are referred to.
