Abstract: Prodn. of polypropylene by polymsn. of propylene at 50 - 100 degrees C under a press. of 20 - 60 atm. in an agitated dry bed of small polypropylene particles in the presence of a Ziegler-Natta catalyst system consisting of (1) 1 mole of TiCl3.1/3 AlCl3 modified by 0.1 - 0.5 mole of phosphoric acid hexamethyltriamide, and (2) 2 - 10 moles of Al trialkyl contg. =3C in each alkyl and introduced into the polymsn. zone in the form of a suspension or soln. in a hydrocarbon medium used in an amt. of 500 - 1000 g. hydrocarbon per mole of Al trialkyl, is improved by using as a hydrocarbon medium 1,2,4-trimethylbenzene opt. mixed with an =4-fold amt. of petrol boiling at 80 - 110 degrees C.
