本文研究了以苯为溶剂、正丁基锂为催化剂,合成分子.量从10~3到10~8的窄分布(分子量分布)聚苯乙烯的反应条件及其与产物分布宽度的关系,得到了分布宽度相当于国外标准样品的合成产品,可以作为凝胶色谱标准样品使用。并订定合成样品的粘度方程,讨论了凝胶色谱对标准样品分布宽度的要求。 In this paper, the reaction conditions of narrow distribution (molecular weight distribution) polystyrenes with benzene as solvent and n-butyl lithium as catalysts for the synthesis of molecules from 10 ~ 3 to 10 ~ 8 and their relationship with product distribution width were studied. The distribution of the equivalent of foreign standard samples of synthetic products, gel chromatography can be used as a standard sample. The viscosity equations of the synthesized samples were also determined. The requirements for the distribution width of the standard samples by gel chromatography were discussed.
