    摘要: C2-C8-Alk-1-enes are polymerized by means of a Ziegler-Natta catalyst system in a reactor cascade comprising at least two reactors, a homo- or copolymer of C2-C8-alk-1-enes being prepared in a reactor RA, upstream of which one or more further reactors may be connected, the reaction mixture being discharged from RA and transferred to a subsequent reactor RB and the polymerization in RB and in the reactors which may be connected to RB being carried out in the presence of a liquid or dissolved regulator for regulating the catalyst activity, by a process in which the regulator is added to the reaction mixture after discharge from RA and before entry into RB, and an apparatus for polymerizing C2-C8-alk-1-enes by means of the novel process is described.
