本工作是甲苯-丁二烯-丁基锂聚合体系研究的一部份。在甲苯溶剂中进行聚丁二烯基锂缔合度测定,在国内外文献上尚未见报导,通过实验可以看出,聚丁二烯基锂甲苯溶液的平均缔合度,在引发剂浓度>1×10~(-3)mol/1范围内等于或大于2,此外用粘度法测定聚丁二烯基锂的缔合度时,如果剪切速度在12～450see~(-1)之间,测量结果不受剪切的影响。 This work is part of the study of toluene-butadiene-butyl lithium polymerization system. In toluene solvent polybutadienyl lithium association degree determination, at home and abroad have not been reported in the literature, we can see from the experiment, polybutadiene lithium toluene solution average association, the initiator concentration> 1 In the range of 10 -3 mol / 1, it is equal to or greater than 2, and when the association degree of polybutadienyl lithium is measured by the viscosity method, if the shear rate is between 12 and 450 seem, the measurement result Not affected by shear.
