A process for homo or copolymerizing propylene, wherein propylene is polymerized in the presence of a catalyst at an elevated temperature in a reaction medium, in which a major part is formed by propylene. The polymerization is carried in at least one slurry reactor in the presence of liquid propylene at a temperature between 80-91 DEG C and a catalyst system producing within said temperature range a high productivity and essentially constant isotacticity within wide melt index range.
