我们根据由薄层色谱法(下称TLC法)测得的R_f可用以表征溶剂对聚合物的溶解能力的观点,以及由此选择氯丁胶粘剂的两组低毒溶剂的结果,认为如果选择一组可对某高聚物作TLC展开的溶剂体系,它们分别具有不同δ值以构成一个溶解度参数谱,测定它们对高聚物的展开结果,其中R_f最大的溶剂体系对它的溶解能力为最大。 Based on the results that R_f measured by thin-layer chromatography (hereinafter referred to as TLC method) can be used to characterize the solvent-dissolving ability of the polymer and thus the two sets of low-toxicity solvents of the neoprene adhesive, it is considered that if one Group can be TLC for the development of a polymer solvent system, which have different δ value to form a solubility parameter spectrum, measured their expansion of the polymer results, including the largest solvent system R_f maximum solubility to it .
