Summary Highly dispersed supported catalysts were prepared by supporting various complexes of CoCl2, CoBr2and NiCl2 on SiO2, MgO, Al2O3 and MgCl2 in n-heptane, followed by evacuating at room temperature. The catalysts combined with AlEt2Cl or Al2Et3Cl3 showed very high activities for cis-1,4-polymerization of 1,3-butadiene. |
