Living copolymerization of ethylene (E) with 4-methyl-1-pentene (4M1P) by an alpha-diimine Ni(II) complex and Et2AlCl as an activator is reported. The living nature of the polymerization was exploited to prepare poly(E-co-4M1P)-block-poly(1-hexene) with low polydispersity index (M-w/M-n approximate to 1.20) and qualitatively good elastomeric properties.
