Process for purifying polypropylene |
| abstract |
Polypropylene obtained by polymerizing propylene in contact with stereospecific catalysts supported on anhydrous magnesium dihalides is purified, and the magnesium content thereof is reduced, by treating a suspension of the polypropylene in a hydrocarbon solvent with an aliphatic alcohol containing from 3 to 8 carbon atoms, followed by centrifuging to remove both the hydrocarbon solvent and the catalyst residues solubilized by the alcohol treatment. |
