Procedure

A solution composed of 10 ml of toluene, 100 ml of hexene, 42.3 mg of this known complex of the formula [Me2Si(Me3SiC5H3)2]NdCl and 20 molar equivalents relative to the neodymium of the co-catalyst consisting of a “BuLi/DiBAH” mixture, with neodymium/BuLi/DiBAH=1/10/10, then 30 ml of butadiene were introduced in succession into a reactor under an argon atmosphere. The temperature of the polymerization reactor was adjusted to 80° C.

Workup
