1-Hexene → Decene-1 hexene-1

Temperature

0 °C

In a glass vessel pre-conditioned by heating under vacuum and filled with argon 0.34 g (1.24 mmol) of bis(cyclooctadiene-1,5)nickel and 0.46 g (1.25 mmol) of bis(trimethylsilyl)amino-bis(trimethylsilylimino)phosphorane were dissolved in 20 ml of decene-1, and the solution was stirred at 0° C. for 3 hours. Then to the gel-like mass there were added 20 ml of hexene-1, and the mixture was stirred at 0° C. for another 4 hours. After a working-up procedure as described in Example 1 there were obtained 24.0 g (85% of the total amount) of a decene-1/hexene-1 block copolymer which had a methyl branching point characteristic corresponding to the molar ratio of the α-olefin reactants (Mn =1 900).
