Abstract: Processing Ziegler-Natta (S-N) catalyst systems contg. (a) a Ti-contg. solid component contg. electron donor(s), in the form of a suspension in inert solvent, and as co-catalyst; (b) an Al cpd.; and (c) opt. other electron donor cpds. comprises removing the solvent from suspension (a) by (1) filtering the suspension and then (2) removing more solvent by applying a pressure difference at not above 100 degrees C. Also claimed are the obtd. catalyst systems.
