用标准样品确定了平均缔合数计算公式中的参数α、g,并对聚丁二烯羧酸锂的平均缔合数进行了测定.发现存在二、四两种缔合体,且其缔合程度与聚丁二烯的分子量、浓度、羧化反应程度有关. The parameters α, g in the calculation formula of the average association number were determined by using standard samples, and the average association number of lithium polybutadienyl carboxylate was determined. Two or four types of associations were found, and their associations The degree of polybutadiene molecular weight, concentration, the degree of carboxylation reaction.
