Abstract: A polypropylene molding composition of polypropylene, ethylene-propylene copolymer and polyethylene having a high hardness and increased impact strength and homogeneity after processing is obtained by way of a continuous three-stage polymerization, when the melt viscosities of the polymer mixtures obtained in the individual stages are in a determined ratio of one to the other.
