| Abstract: | The interaction enthalpies and Flory-Huggins parameters wre determined for a scries of probes with different properties in PEO, PVAc, KH-560, ND-43, PMA, and three kinds of acrylatc-4-vinylpyridine copolymer systems by inverse gas chromatography (IGC). The Drago s E, C parameters of PEO, ND-43, and the copolymers were also determined by IGC. The results show that the acid-base interaction has a considerable influence on the intermolecular interaction in the condensed state and the adhesive property between polymers and fillers. The solubility of polymers is also influenced by the acid-base property of polymers and the acid-base interaction. In this work, We have devised a convenient method for characterizing the acid-base properly of polymers and the acid-base interaction of polymer systems |
