Block copolymerization of propene and 1,5‐hexadiene was carried out by a modified stopped‐flow polymerization method with an MgCl 2 ‐supported Ziegler catalyst. The resulting polymer, polypropene‐ block ‐poly(methylene‐1,3‐cyclopentane‐ co ‐propene) (PP‐ b ‐(PMCP‐ co ‐PP)), in which the crystallizable PP part was linked with the non‐crystallizable PMCP‐ co ‐PP part, was characterized by optical microscopy, differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA) and tensile testing. The block copolymer having a chemical linkage between PP and PMCP‐ co ‐PP showed properties different from those of homopolymer, random copolymer and blend polymer. © 2001 Society of Chemical Industry
