The solubilities of ROK in several different solvents such as toluene, ether, THF and 2G were studied. Considering the influence of solvent on the microstructure of telomers, THF was determined to be the best solvent.In the system of n-BuLi/ROK/xylene/2G/olefin, the influence of ROK on diolefin anionic telomerization was investigated, and the result shows that the difference between butadiene system and isoprene system was little.
