Abstract: The present invention relates to an olefin polymerization process, wherein propylene and a C4 to C10 α-olefin monomer, preferably 1-butene- and optionally ethylene are reacted in the presence of a Ziegler-Natta catalyst so as to obtain a polypropylene, wherein the polypropylene comprises C4 to C10 α-olefin, preferably 1-butene-derived comonomer units in an amount of from 0,5 to 15 wt % and ethylene-derived comonomer units in an amount of 0 to 3 wt %, and wherein the Ziegler-Natta catalyst comprises i) an external donor of the formula (I): (R3)z(R2O)ySi(R1)x, and ii) a solid catalyst component being free of external carrier material.
