本文讨论了用薄层色谱法(下称 TLC)测得的流动比率R_f和溶剂对高分子溶解能力之间的关系,提出了用R_f表征溶剂对高分子的溶解能力。根据此方法选择了两组氯丁胶粘剂的低毒溶剂。
This article discusses the relationship between the flow ratio R_f measured by thin-layer chromatography (TLC) and the solvent’s ability to dissolve the polymer, and suggests that Rf be used to characterize the solvent’s ability to dissolve the polymer. According to this method, two sets of low toxicity solvents of neoprene adhesive were chosen.
