Urazbaev Butadiene polymerization in cyclohexane, carried out on NdCh3nL catalytic system (n = 3, L = 1-pentanol, 2-pentanol and 3-pentanol) and triethylaluminum as co-catalyst, was studied [60]. The highest catalytic activity was displayed by the system with 2-pe:ntanol and then, in descending order, with 1-pentanol and 3-pentanol. The polymer yield increased with the catalyst and co-catalyst concentration, as well as with temperature. Hence, characteristic viscosity reduced in this case. Microstructure of polybutadiene formed was independent of the above-listed factors; the content of 1,4-cis-units exceeded 99%.
