摘要
本工作利用反气相色谱技术,研究了一系列不同性质的探针分子与PEO,PVAc,CPE,PMA等均聚物,几种丙烯酸甲酯-4-乙烯基吡啶共聚物,以及南大-43,KH-560等偶联剂的相互作用.结果表明,酸碱作用对凝集态中相异分子间的相互作用有显著贡献,本工作建立了一个较为简便的测算聚合物和偶联剂的Drago参数,定量表征聚合物和偶联剂的酸碱性质的方法.
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
