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.
考察了不同ROK在甲苯、乙醚、四氢呋喃及二乙二醇二甲醚(2G)等不同溶剂中溶解能力,又考虑到溶剂对聚合物结构的影响,以及工业化的难易程度等方面,最终确定了ROK的最佳溶剂为THF。
