Embodiment Construction
[0018] exist figure 1 In an embodiment, the slurry polymerization is carried out in a jacketed loop reactor, designated 10. Schematically, catalyst components, co-catalysts, and monomers (such as propylene) are introduced into the loop reactor in the direction indicated by arrow 12 . Including loaded with active MgCl 2 In cases where a Ziegler / Natta catalyst on a solid component is used, the solid component can be fed in as such or, preferably, in prepolymerized form.
[0019] Loop reactor 10 may be the first polymerization reactor of the process, or there may be other polymerization reactors upstream of reactor 10 . For purposes of the present description, reactor 10 may receive from line 12 polymer produced in other reactors, or receive prepolymer and / or polymerization catalyst or catalyst components. exist figure 1 The feed lines for catalyst, monomer, molecular weight regulator and other possible ingredients have been omitted in the simplified diagram of , since they a...
