摘要
Acid-base theory is an important method to describe the interaction between materials. The inverse gas chromatography (IGC) technique can be used to measure the surface Lewis acid-base parameters of materials. Compared with the solubility parameter method, the merit of the IGC technique is that it can give the surface acid-base properties of many undissolvable materials, such as inorganic materials, metal-oxides, and thermosetting polymers. In this paper, six polymers are chosen to discuss the rationality of their Lewis acid-base parameters from the molecular structure viewpoint. Compared with some small molecules, the values of these polymers are reasonable. However, endowing each group with a set of acid-base parameters is impossible at this stage because of the lack of sufficient data. Thus more characterization work is needed to develop the IGC method.
