Abstract

AbstractThe short‐period polymerization method was successfully applied to the synthesis of a novel diblock copolymer, polypropene‐block‐poly(ethylene‐co‐propene). The polymerization was carried out for ca. 0,1 s with a MgCl2‐supported Ziegler catalyst. The copolymers obtained showed unimodal curves in gel‐permeation chromatography without any peak in the low‐molecular‐weight region. After extraction with heptane, the fraction of poly(ethylene‐co‐propene) remained unchanged in the copolymer but disappeared in a commercial so‐called block‐type copolymer. All the results the formation of polypropene‐block‐poly(ethylene‐co‐propene), in which poly(ethylene‐co‐propene) is chemically linked with polypropene.
