A process for producing propylene homopolymers comprises producing a homopolymer in a reactor train having a first stage and a second stage, wherein the first stage is normally used for homopolymer production and the second stage is normally used only in the production of copolymer blends, and is left idle during homopolymer production. According to the invention, during the production of propylene homopolymer, the polymerization is carried out sequentially in both the first stage and second stage reactors.
